1. Suppose we are dealt 7 cards from a well-shuffled standard deck. (You may leave terms like (2) in your answer.) (a) What is the probability of 3 pairs? (b) What is the probability of 4 of one kind and 3 of another? (c) What is the probability of 4 aces and 3 of another kind? (d) What is the probability of all seven cards being in the same suit? (e) Let N be the number of aces that you are dealt. What is P{N = k} for k = 0, 1, 2, 3, 4. (You could work this out for each value of k, which is fine. However, you might also be able to figure out how to write your answer as a function of k, which involves a lot less writing.)
