Two cards are selected from an ordinary deck of 52 cards. Assume that the first card is not replaced before the second one is drawn. Consider the following events: A = {first card is an ace) and B = {second car is an ace). (a) Find P(A and B) (b) Find P(B) Hint: consider the complement of A. Then B = {A and B) or {A' and B} (c) Find P(A or B)
