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?

Easy

so remember

4 aces in a deck

probability = (desired outcomes) / (total possible)

total possible=52

4/52=1st card

then since he picked 1 out the total possible is and assuming he drwe an ace 3/51

so the answer is 4/52 times 3/51=1/221
