there are 52 cards total in a deck. how many kings/queens are there?
4 suits, 1king/queen for each suit, so there are 4 each
the probability to get a king from a full deck of 52 is 4/52 =1/13
after the king is drawn there are 51 cards in the deck. the probability for drawing a queen is then 4/51
what is the probability of the first card being a king and the second card being a queen?
Ptotal = P(getting a king in a deck of 52) x P(getting a queen in a deck of 51)
