A standard deck of cards is being used to play a game. There are four suits (hearts, diamonds, clubs, and spades), each having 13 faces (ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack queen, and king), making a total of 52 cards. This complete deck is thoroughly mixed, and you will receive the first 2 cards from the deck without replacement. Complete parts (a) through (c). a. What is the probability that both cards are hearts? P(both hearts) = (Round to four decimal places as needed.) b. What is the probability that the first card is a 9 and the second card is a 5 or a 6? P(9 followed by 5 or 6) = | | (Round to four decimal places as needed.)
