61. Suppose in Exercise 29 that the shooting ends when the target has been hit twice.

Let mi denote the mean number of shots needed for the ?rst hit when player i shoots ?rst, i = 1, 2. Also, let Pi , i = 1, 2, denote the probability that the ?rst hit is by player 1, when player i shoots ?rst.

(a) Find m1 and m2.

(b) Find P1 and P2.

For the remainder of the problem, assume that player 1 shoots ?rst.

(d) Find the probability that both hits were by 1.

(e) Find the probability that both hits were by 2.

(f) Find the mean number of shots taken.
