Question

Don randomly draws two cards from a standard deck of 52 cards. He does not replace the first card. What is the probability that both cards are aces?

Answer 1

1st pick there are 4 aces and 52 cards so a 4/52 chance ( reduces to 1/13)

2nd pick there are 3 aces and 51 cards so a 3/51 chance ( reduces to 1/17)

1/13 x 1/17 = 1/221 probability
