Basically it leads you on to the goat problem method but that method fails in this case.
Since the gold ball is predetirmined.
>>
>>515316054
if you pulled out a gold ball, then there's a 2/3 chance that it came from the 2 gold ball box and a 1/3 chance that it came from the 1 gold ball box

so there's a 2/3 chance the other ball is gold and a 1/3 chance that the other is silver
>>
>>515317303
>>515318208
if it helps imagine that the boxes have 1 million balls each

box A has 1 million gold balls
box B has 1 gold ball and 999,999 silver balls
box C has 1 million silver balls

you pulled a gold ball, what's the chance the other is gold? practically 100% because it's way more likely that you pulled a gold ball from box A than the 1 gold ball from box B

It's counterintuitive because you could have pulled any of the two gold balls so there are three possible outcomes instead of only two. Dosent mean that people who don't see it st first are stupid. It's those who refuse to understand it who are. Also the answer is 66.666% not 60

>>
>>515318643
that is not true, you are taking the probability at the wrong time and factoring in things that are simply not a factor.

You have an equal chance of either even in this case, its still a coin flip, you simply cannot understand this because you are stuck trying to measure something the wrong way and wont admit you might be wrong.

It helps visualize conditional probability. But it says nothing about initial conditions.

We dont calculate the odds of American and Croatian meeting in Cambodia at 17 pm south asian time etc.
We look at odds of a penny flip that is 50/50.
>>
>>515319356
The silver ball box is completely irrelevent once the riddle says you pick a gold ball. After that, you have only 2 boxes which have 3 balls, 2 gold and one silver. In what universe is that a 50/50 split?
>>
>>515319308
no, but it would be nice if they did.
>>
>>515316054
If you pick box at random then we have to take all gold balls and all silver balls which is 3 and 3.
Box is 1/3
Ball is 3/6
So around 33% for silver.

Now thinking about this if balls are made by volume and not by weight then gold would be heavier and thus you could easily cheat. If taking it to the hands if you had a chance.
>>
>>515316054
It is one in three if I am not mistaken. The third box is excluded. We do not know if you pulled box one or two, but we know there is two gold balls and one silver ball remaining, thus one in three. Or am I just retarded?

>>515319850
It is irrelevant. Let’s use two boxes instead. No box with silver/silver.

Gold/gold 1/4
Gold/gold 1/4
Gold/silver 1/4
Silver/gold 1/4

We have no silver/silver box.

Probability of picking gold P(A) = 3/4
Probability of picking gold followed by silver P(A n B) = 1/4.

(1/4)/(3/4) =0,333
>>
It is 50%
Bless your hearts
>>
first ball is gold
you are pulling from one of the left two boxes
there were 4 balls in those two boxes to start
one of those balls is silver
therefore the probability of pulling the silver ball is 1/4 or 25%

>>
didn't read any of the posts but i remember seeing the story about some math genius woman getting shit on by a math professor about this.
the math professor guy was adamant about choosing another box after you pulled the first box would do nothing to change your odds, whereas the genius lady said even after you removed the first box your odds were still 1/3 but it would become 1/2 if you chose again.
which seems counterintuitive but the lady was apparently right.
>>
>>515321220
Because you need to calculate the probability of pulling from one those boxes and pulling gold first.

The likelyhood of pulling gold first is not the same in the second box as in the first box.

Thus you need the calculate the probability of drawing gold first and silver second knowing you have drawn gold first. This is not 50 % because the likelyhood of your hand being in gold/gold box is greater than gold/silver box.
>>
>>515321421
it doesn't matter how many are left, retard
only how many were originally in the left two boxes

it's 1 in two lol.
The ball you picked is gold, which means you picked either box A or B. Now you have 50% odds to be in B (silver)

No you don't, pulling a gold ball is a certainty as formulated by the problem. You never encounter box C, it might as well not exist

at the outset you have a 50% chance of picking either after you remove one gold ball the probability rises your next selection will be a silver ball.. the querry doesn't ask for a specific percentage but its a two to three ratio
>>
Let’s rephrase the problem so everybody understand: there are two gold balls in box A and 1 gold ball and 1 silver ball in box B. You put your hand in one box and draw a gold ball? In which box is your hand (most likely)?

>Should someone's proficiency in logic and reasoning determine whether they get to vote or not?
Yes.
/thread
>>
>>515322154
No, because you're taking a gold ball. Each box has equal probability to get picked (except for C which cannot be picked). So picking a box with a gold ball is one in two. It's not conditional probabilities since you know P(box picked contains gold ball) = 1

Basically the problem is awkwardly formulated and therefore there's not reason to argue it, but if you strictly follow the words of the problem, I'm right
>>
>>515322541
The answer to OP's original question is "Yes".
But your answer to the picrel is wrong.
Picking the first ball is really a matter of picking a box.
The odds that you're holding the box with two gold balls is twice the odds that you're holding the box with only one.
That means it's twice as likely that the other ball will be gold.
>>
>>515322688
The problem starts at "it's a gold ball". Anything before that is in the past and therefore misdirection. Again, it's a silly facebook-tier problem like the one with the division so who cares

>Le problème consiste à sélectionner une boîte, à y tirer une des deux médailles au hasard puis, si la médaille tirée est en or, à calculer la probabilité que la seconde médaille tirée de la même boîte soit également une médaille en or[1]. Intuitivement, il pourrait sembler que la probabilité que la médaille restante soit en or est de 1/2 : mais elle est en réalité de 2/3. Ce paradoxe est un biais d'équiprobabilité.
Betrand formulated as "if it's a gold ball, what is the probability that the neighboring ball is also a gold ball". In that case it's conditional probabilities. As I've said, OP's thread is badly formulated.

ok but can you admit that you were wrong regarding the solution of the problem as it was formulated?
>>
>>515323689
As the question is formulated, the probability that the next ball I take from the same box will be silver is 1/3.
I picked a box at random. I put my hand in and took a ball from that box at random. It's a gold ball. That leaves me with three scenarios:
(GG Box - balls G1 and G2)
(GS Box - balls G3 and S1)
I picked G1.
I picked G2.
or
I picked G3.
That's three scenarios, with three separate following scenarios.
If I picked G1, the other ball is G2.
if I picked G2, the other ball is G1.
if I picked G3, the other ball is S1.
That's two scenarios where the other ball is gold, one where it is silver.
1/3.

Thank you for your service, Hans. If the last thread was any indication you’ll have 90IQ midwits spouting off about “which” gold ball you picked as though it actually matters because they can’t read and see that the problem starts AFTER the gold ball is chosen and everything before it is fluff. In fact, here’s one now
>>515323962
At the time that the OP question is asked, there are precisely two options. You are holding a gold ball and in front of you is a box that either contains another gold ball or a silver ball. HOW you got to this point is irrelevant. If you can’t see why you’re the one getting filtered by the election IQ test
>>
>>515323962
You didn't pick a ball, you picked a box. The gold ball has already been picked. There were two boxes with a gold ball. The third box doesn't exist. The boxes are picked at random and therefore P(A)=P(B)=0.5
Again, we're arguing about nothing. You'd be right if the problem, as it should've been, was formulated as "if you pick a gold ball, what are the odds the next ball is gold". But it wasn't.

What neither of you are getting is that it's twice as likely you're holding a box with two gold balls than a box with only one.

I already have a gold ball and I'm not a greedy kike. I do a 360 and walk away from the Jew boxes so zero percent.

Let's say we have three boxes. One with three gold balls. One with two silver balls and a gold ball. One with three gold balls.
You pick a box. You choose a gold ball. Which is more likely - that you picked a gold ball out of the box with three gold balls or that you picked the gold ball out of the box with two silver ones as well?
Given that, if you take another ball, which is more likely - that the ball will be gold or silver?
Keep adding balls to the situation until it makes sense. It's a question of the probability of which box you've chosen.

Yes, this would be the case if you were looking at closed boxes with 2 gold balls, one gold and a silver ball, and 2 silver balls. But you're not, you're looking at one box and you have one gold ball in your hand.

it doesn't matter what was the likeliness of an event in the past to happen. The problem starts with you having a gold ball, how you got there is irrelevant.
The problem isn't "what were the odds that you picked a silver ball after drawing a gold ball from one of these 3 equiprobable boxes", it's "what are the odds your next ball is silver"
>>
>>515325299
but you are twice as likely to have picked the box with 2 gold balls
>>

Can I get a concession?
>>
>>515319850
You keep missing what happens and cannot follow along. You are acting like you can draw from another box, rather then being forced to draw the 2nd ball out of the box you already drew from.

You already have chosen the box to draw from and you ALREADY have taken a gold ball out of that box. This affects the probability of what comes next.

The only two possibilities are there is one gold, or one silver ball left in the box. Even with n-infinity balls, you still already chose either the box that will produce a silver or a gold ball, its still a coin flip

try the experiment in real life and see what your results are, do it with 10 balls so that the retard "mathematicians" in this thread would say you have a much higher chance of drawing a 2nd gold ball.

You will find that the average tends towards 50% given a large enough sample size.

The simple fact is that most people do not understand that once you take a single gold ball, out of an unknown box, you actually have only one ball left inside that same box. The ball, that you will 100% not pick, in another box you will 100% not pick from, is 100% irrelevant to the probability of the 2nd ball being picked from the box you pulled a gold ball out of.

You have only two options for the 2nd ball from the same box, either it is silver, or it is gold. You cannot somehow pick the "3rd gold" from a different box at that point hence why it isnt a factor for the actual math.
>>
>>515325065
>>515325317
You are both literally adding conditions to the matter that are not in the initial problem.
Every step matters.
Again, let's say you have two boxes. One has 100 gold balls. The other has 1 gold ball and 99 silver ones.
You pick a box at random.
You pull out a ball.
It is gold.
Given the problem where it stands now, you draw another ball.
What is the probability that the ball is silver?

You have chosen a box. God Himself has ensured that when you reach into that box you grab a gold ball. At that point the box in front of you either has 99 gold balls or 99 silver balls. What is the chance of either happening?

>God Himself has ensured that when you reach into that box you grab a gold ball.
This is the mistake you're making. That's not in the initial question at all.
There was a probability involved of you pulling a gold ball out of that box. Your "answer" requires ignoring that.
I'm going to give you the benefit of the doubt and say you're trolling, because otherwise you're not even a midwit - you're a retard.
>>
It’s not a statistics exercise it’s a thought exercise in predetermined outcomes vs. observed results.
You can say 1/3 and be correct because you chose randomly from 3 boxes and only 1 in 3 contain both the silver and gold ball.
You can also say 1/2 and be correct because after you’ve observed a gold ball, you know you’ve selected one of the two boxes containing gold balls and only one of the two possible boxes remaining has a silver ball.
The question is left intentionally ambiguous to spark a discussion between these two approaches. It’s contingent on whether / when you disregard the box with both silver balls. If you’re taking that box out of the equation you’re positing that your fate was predetermined and you may very well be correct because you didn’t pick it - your odds are 1/2 and were always 1/2 because with the information you have now, you know the box with both silver balls was never going to be the result. On the other hand, your selection was random, you could have picked the box with both silver balls, you didn’t, but it was always a possibility and the outcome was decided by random chance.

And that probability is 1. Because you are TOLD it’s a gold ball

>>515326446
It's not 1/3rd because there are three boxes.
It would still be 1/3rd even if there were only two boxes you could have picked from initially.
It's 1/3rd because, given you pulled a gold ball, it's twice as likely you pulled it from the box with two of them than the box with only one.

Does this new information change the probabilities involved? Why or why not?

That’s where you are wrong. Since the probability of box A is greater than box B.

You can take this to an absurd level if you still don’t understand where you are wrong:

Box B have 1 gold ball and 999 silver ball.

You're answering 'if you pull a gold ball, what's the chance the next oneis gold?' But the question is 'you pulled a gold ball. what's the chance the next is gold?

In the latter case, youre either pulling a ball from 100% gold balls left or 100% silver balls left
>>
>>515327425
Why would you change the ratio of gold balls to silver? Box B is half gold half silver. This information is given, it’s not up for debate.
>>
>>515320256
Very close but missing the key component. If you pulled a gold ball then you have 2 options left. One gold or one grey. It's 50:50

there are only two boxes as the box with the silver balls has been eliminated. with only two boxes the answer to the meme can only ever be 50%.

>>515318643
But box B would have 500,000 gold and 500,000 silver in order to be equivalent.

The answer is you have a 50 percent chance of getting a silver ball. Since you either have the gold ball from the dual gold box or the one from the gold/silver box.

The ratio was skewed as to make it absolutely apparent that the probability of having picked A is higher than B if you have picked a gold ball.

Niggers here can't into already established new conditions. You already picked a gold ball, you are already in a situation where you are either in box A or box B, with no way to know. This is an either probability between 2 choices with nothing distinguishing them, therefore a 50%.

>>515329162
Yes, I know that. But doing so results in 2/3. Because by ignoring silver, you are throwing away 50% of the occurrences of the second box. Basically, each box is equally likely, if you select the third box you then throw it away 100% of the time, the second box you throw away 50% of the time, and the first box you always keep. This results in the first box being twice as likely after applying the gold condition.

And what about the box with both silver balls? You chose at random. You didn’t pick box C but you very well could have. Were you always destined to pick either A or B? If you do the exact same exercise a thousand or a million times will you always pick either A or B?

>>515327425
The original choice was 50/50 between a gold and silver ball, brainlet. You never had a higher chance to get anything. Either type of ball could have come out of 2/3 of the boxes. The only way to get gold being more likely is if you pretend there never was a box that contained 1 of each. You have no clue which of the 2 boxes you got your gold ball from nor is there any way to estimate that without making assumptions on shaky grounds.

>>515329751

It doesn't matter; We are already told what happened, we picked a gold ball, box C is totally irrelevant. We picked a gold ball, it could have come from either box A or B. With no further information, it's 50/50. Either we picked from A and it's 100% of gold ball next, or it's B and 0% next.

You've got to be trolling to not understand that kind of scenario. "You toss a coin and land on heads, what are the chances of landing on tails if you toss a coin again?" It's 50%, retard, the previous state is already set in stone and clearly told as such, going into "but what if I landed on tails before?" rants is irrelevant.

you're pulling from the same box. There is only one ball left in that box. You will 100% pull out the remaining ball from a box that contained at least one gold ball. Since there are two of those boxes, the answer is 50%.
>>515321591
it doesn't matter what the probability of the first pull is. You are told the result. You have pulled a gold ball. Even if the situation is as another anon put it where there are a million balls in each box, one box all gold, another box 1 gold and remaining silver. You are told the first pull is gold. The answer is 50% regardless. It's not about the remaining balls, but about the binary odds of which box you pulled from initially and since it's random it's 50%

there are 6 different outcomes
GG,GG(reversed order), GS, SG, SS, SS(reversed order)

The 3 outcomes are
(a)Gold then Gold
(b)Gold then Silver

This explains it perfectly. You don't know which ball you pulled exactly and it could have been one of the two from Box A or the one from Box B.

>>515331094
it matters for the odds of picking an initial gold ball. The questions asks what are the odds of the colour of the remaining ball in the box you already opened. There are only two outcomes since there is no universe that exists where you picked the box with only 2 silver balls. You either picked box A or B. You find out when picking the 2nd ball. That is the question. The odds of the initial pick are irrelevant. It could be 1 gold ball to 20 quintillion silver balls in box B. If you are told the first pull is gold it is still 50/50 which fucking box you pulled from

Here's a question for you. You have won the lottery, you flip a coin heads or tails, what are the odds the flip is heads? Is the answer one in 100 million because that is the odds of winning the lottery? No retard. It's irrelevant and built into the hypothetical that it already happened

How can you expect to do maths when you when you can't even read?

You miss the whole point.
The point of the problem is figuring out the probability that we picked a particular box in the first place.
Odds are 0/3 that it was the SS box. 1/3 that it was the GS box. 2/3 that it was the GG box.
Given that, it is more likely that the other ball will be gold.
>>
>>515329978
If you ignore the setup you can make the result anything you want. The setup tells you to perform a random selection, but if you ignore that, then you could do whatever you want, such as always selecting the first box. You cannot ignore the setup.

There's only 2 real possibilities

They think that the puzzle is "You are holding a gold ball which came from either a box with GG or a box with SG"

They ignore the process to get to that situation because they think it's irrelevant, but they're wrong.

There are three gold balls you could have picked. A, B, C. A and B are together. C is with the silver ball, D. If you picked A, then the other ball is B (gold). If you picked B, then the other ball is A (gold). If you picked C, then the other ball is D (silver). 1 silver, 2 gold, 1/3 probability of getting silver on second try.

but it doesnt matter. The initial box pull was random so the odds of any box being involved is 1/3. It doesnt matter what colour the initial ball is since the question is mirrored. If it was silver it would involve boxes B,C, but it's gold so it involves boxes A,B. you eliminate one of the boxes as an option. You have two boxes left which each had 1/3 of a chance of being involved in your initial pick. Now since those odds are even it's 50/50 which box you are pulling from. Unless your goal from the very start was to pull gold balls in which case it's a different question.

Mathematics degree holder here. The answer is 50%, because you can't change boxes. You either grabbed the gold ball from the box with 2 or you grabbed the gold ball from the box with 1. This isn't a monty hall problem like I see some anons absentmindedly commenting. In probability this is using the "given" notion, which restricts the probability domain, which the monty hall problem utilizes in successive probability scenarios and results in the unintuitive outcome of greater success odds for switching doors. Probability regularly finds itself falling at odds with intuitive outcomes, because we generally don't think to restrict the domain of possible outcomes as we must to properly calculate probability.
>>
>>515331882
now make a simulation where you have two boxes, one has a gold ball, the other a silver and ask it to give it the results. Y'know, since thats the question since the initial pull is irrelevant except to eliminate the third box from the question. You have picked up a gold ball. There is no universe where you havent.

Probability of gold as first pick = 3/4. Probability of silver second (1/4)/(3/4) =0,333.

Unfortunately some people haven’t though this through.

Like someone else said. They believe the path doesn’t matter, when it really does and have been proven to matter experimentally.

The argument that ”if” matters is basically a LGBTQ based argument. Hard fact doesn’t care.

>>515332535
Each box is 1/3 before the constraint. The constraint filters away some of the probability of each box. The gold constraint filters away all the probability of the third box, making it 0. The same mechanism that makes the third box 0, acts on the second box reducing it from 1/3 to 1/6. After re-normalization of the remaining probabilities 1/3, 1/6,0 becomes 2/3, 1/3, 0.

You have no issue with the third box being reduced to zero. That same process acts on the second box 50% of the time, cutting its probability in half.

This isnt so much a logic problem as a listening problem. 2 Boxes have at least 1 gold ball, so if you put your hand in and draw a gold ball and then go for another one IN THE SAME BOX, then this elimenates the double silver box because you only put your hand in the 1G1S or 2G, therefore you have a 50% chance of pulling a silver ball out since you can only draw a gold or silver ball next.

>>515333255
it is stated as a condition in the question that you have obtained a gold ball. It does not matter what the odds of getting that gold ball are to the actual question. Box B could have contained 1 gold ball and 20 million squitillion silver balls. The hypothetical states you have obtained a gold ball. There are only two boxes where this is possible and until you pull a 2nd ball it is unknown which one you have picked. Therefore the odds are 50/50. The balls and their counts are irrelevant except in removing box C from contention.

>>515333728
>The hypothetical states you have obtained a gold ball. There are only two boxes where this is possible and until you pull a 2nd ball it is unknown which one you have picked. Therefore the odds are 50/50.
You obviously do not understand the position you are arguing against.
You picked a box. You pull out a gold ball.
Which gold ball did you pull out?
There are three possible scenarios.
A) It was the first gold ball in Box A, leaving the second gold ball.
B) It was the second gold ball in Box A, leaving the first gold ball.
C) It was the gold ball in Box B, leaving a silver ball.

Somewhere in your logic you are conflating scenarios, either by assuming scenario A is the same as B or that scenario A is the same as C. It's not. Either way, you only get 50/50 by artificially eliminating one of the scenarios.
Again, it's not that we can't read - it's that your appraisal of the possible scenarios at hand somewhere conflates two of them, eliminating one.

no, there's only 2 boxes containin gold pcs. drawing from the same box again, chances are it's either the 2pc gold box or the 1pc gold box. so 50% it is.

Look at all these gay replies, talking about balls!

50%, since you already know it can't be the box with 2 silver balls, so 2 possible boxes are left.
Before taking the first ball, the possibility is 1/3, since you don't know what the first ball is gonna be.

If you throw them in the 3 boxes randomly, there's a 3/6*2/5 =1/5 chance that a box has two gold balls and a 2*3/6*3/5 = 3/5 chance that it has one of both kinds. Therefore, if you pick a gold ball, there's a 3/5 * 1/2 / (3/5 * 1/2 + 1/5) = 3/5 chance that the next ball is silver. If you just put them in order, it's the same as in OP, 1/3.
>>
>>515334340
Indeed I have. Now which box did I pick? The one with two gold balls or the one with one gold ball and one silver ball.

This is fairly easy to deduce. The number of possible outcomes:

Box A
Gg
gG
Box B
Gs
Sg

I pick gold as first pick. I have 2/3 probability to have picked A and 1/3 probability to have picked box B.

From this hard fact we can deduce it’s 1/3 probability the next ball will be silver.

because it has already happen in the past. It's no longer up in the air. We restrained the probability domain

>>515334848
It has narrowed but not to the extent you insist.
That's the mistake you are making.
It's narrowed down to which box is it more likely that we have - given that we drew a gold ball, is it more likely that we have the box with two of them or that we *happened* to draw the gold ball from the box with only one.
>>
>>515317938
no you should tighten them
>>
>>515334724
there's only one possible distribution of the 6pcs over 3 boxes. no matter the packing sequence, you'll always come up with the same result. 2/2;1/2;0/2. which given your first draw is gold, leaves a 50% chance for drawing gold from the same box.
>>
>>515334731
>Now which box did I pick
One of the two boxes that had a gold ball in it.

Do you not understand that "IF you pick a gold ball then" and "you HAVE picked a gold ball, so" are different problems?
>>
>>515334899
It is though, because we don't know which box we chose.
That's the point of the exercise.
We don't have Box 3.
Saying that the ball will be "gold" means we have Box 1.
Saying that the ball will be "silver" means we have Box 2.
If we pull gold, the odds we have Box 1 are 2/3 since two of the three gold balls are in there. There's only a 1/3 chance that we had actually picked Box 2.
You're dismissing the very thing we're trying to determine.

That's wrong. Imagine if the first box had 10 gold balls instead. The probability for the second ball to be silver would still be 1/3, despite the first box being Ggggggggg gGggggg etc.

Here’s the problem in a way even a retard can understand;

Box B one gold ball and one silver ball

Well seeing box A have two gold balls, while B have one, it seems more likely my hand is in A.

You're getting hung up on the initial setup and ignoring the partial outcome you already have.

The question you are answering is "What are the odds of you having picked a box with two gold balls if you have already picked a gold ball from that box?"

When you pick up a ball, all the options are still open. When you realise that the ball is golden, it gives you information about which of the random universes or futures you've ended up in. Now some of them are more likely than others, and some are entirely out of the question. For instance, once you realise that the ball is golden, you know that you're not in a universe where you chose the third box.

the hypothetical is badly formulated. It is not the Monty Hall problem.

You have a golden ball. You are not seeking golden balls. You just have picked a ball from a box at random and the colour split is 50/50 so you're just as likely to have any colour in your hand. It just happens to be golden. The only thing you know from this is that since one of the balls is golden it cannot have come from box c where bother were silver. Beyond that you have no idea about the boxes because they are identical except one now only has one ball. I cannot stress any more that the question in OP's picture is BADLY FORMULATED. It looks like something it isnt. Try reading it again with that understanding.

Well if you enumerate all the possible universes, the probabilities should even out in all cases. E.g., if you pick a gold ball, you know you're not in the universe where you picked box 3. And if you picked a silver ball, you know you didn't pick box 1. If, after picking a golden ball, the probability were split 50/60 between box 1 and box 2, and, if, after picking a silver ball, the probability were 50/50 between box 2 and box 3, you notice that box 2 is the most probable universe of all, don't you? But since all boxes should be equally likely, the 50/50 result must be wrong.

A false positive of 5 % means that if you're healthy, the test has a 5 % chance to label you as sick anyway.

The correct answer is 20/1019 ≈ 2 %. It's the exact same Bayesian probability you'd use to figure out OP's question too, so I thought it'd be relevant here.
>>
>>515337711
its not relevant and youre braindead. 50% is correct answer and there is no other even hypothetical answer.

The problem is with the question.
It allows dirty foeriegners to misread it and assume they know what it is asking, then they can persist in fallacious arguments, when in fact it is capable of being read as ambiguous as to at what point the question begins and the probability should be calculated.
Everything that results is based on this.

again for some reason you're shoehorning in some sort of probability from the first ball. This one makes no sense but the impulse is the same. Just reread the question in OP's picture and keep in mind it was written by an idiot.

Where the fuck did the 20 come from?

It's just a prettier way to write the fraction.
1/1000 chance that you have the disease and a positive result
5/100 * 999/1000 chance that you have a positive result but no disease
1/1000 + 5/100 * 999/1000 that there's a positive result
The chance that you have the disease is (1/1000)/(1/1000 + 5/100 * 999/1000) = 20/1019
>>
>>515337924
I showed a contradiction in your result, though.
If you have a gold ball, it's 50/50 between box 1 and and box 2
If you have a silver ball, it's 50/50 between box 2 and box 3
These are the only possible universes, of course, since there are only silver and gold balls. But you notice that box 2 is the most probable of these unvierses, being twice as probable as either of the two others. That's a contradiction. Therefore, 50/50 is wrong.
>>
>>515337711
This did not clarify anything.
If we have 100 different people with positive test results, the expectation is 5 are false positives.

If we pick one at random, there is a 95% chance they did have the illness.
