Elementary school students solve this.

In the first grade.

It's 100%. If you've already drawn a card the probability of that card being the card it is and not some other card is 100%.

2 1 3
>draws 2
1 3

is it 1/2? this seems to be deceptively simple.

It's ambiguously worded. For example l, draw 2 of the cards, not 2 the nunber

This is worded weird.
"What is the probability that you do not draw one (card) if you draw two (cards)"
100% because you drew one two cards.

"What is the probability that you do not draw (the card numbered) one if you draw two (cards)"
66%

"What is the probability that you do not draw (the card numbered) one if you draw (the card numbered) two"
50%

If you draw two cards, the probability of leaving #1 should be the same as the probability of leaving #2 which should be the same as the probability of leaving #3. So it should be 1/3, not 66%

this is why school is bullshit
