5.37. A deck of cards is shuffled and the top eight cards are turned over. (a) What is the probability that the king of hearts is visible? (b) A second deck is shuffled and its top eight cards are turned over. What is the probability that a visible card from the first deck matches a visible card from the second deck? (Note that this is slightly different from Example 5.39 because the cards in the second deck are not being replaced.)
