Two cards are drawn without replacement from an ordinary deck of 52 playing cards. What is the probability that both cards are kings if the first card drawn was a king?
I'm thinking its 13/51 but not sure.

the probability of obtaining exactly two 5's in six rolls of a fair die

13/52 * 12/51. W/o replacement means the second king would have l less in both the numerator and denominator so multiply the 2 results.

If you randomly select a card from a wellshuffled standard deck of 52 cards, what is the probability that the card you select is a heart or 10?
