Because the two drawings are made from a complete deck of cards, the two events are independent of one another. You first need to determine the probability of drawing a card of twosuits from a deck of cards. Out of a total of 52 cards, there are 13 cards of any suit and 26 cards of a black suit. The probability of drawing a card of a black suit, P(A), is 26/52. Because the first card is replaced before the second drawing, the probability of drawing a card of the same suit, P(B), is also 26/52. Thus, the probability of drawing two cards of the same suit is
