Chapter 9.4, Problem 16MS

House of cards. Your friend hands you a deck of 52 cards along with the histogram below. It shows the results for hearts if a card is chosen at random from the deck, its rank recorded ( A, 2,3, . . ., 10, J, 0, K ) , the card replaced, and then the process repeated 4000 times. How do you know the heart suit in the deck is incomplete? Which heart cards are duplicated in the deck? How many duplicates do you think there are?
