sophia shuffled a deck of 52 playing cards and had her friend greenlee draw 1 card without looking sophia put the card back in the deck without looking what is the probability that both cards greenlee drew were kings

P(K) = 4/52 = 1/13

If the card was replaced before the 2nd draw, then
P(K,K) = 1/13 * 1/13
If not replaced, then
P(K,K) = 4/52 * 3/51 = 1/13 * 1/17
