(c) The outcome must be A on the first spin and B on the second, each with probability 1/3.

ANSWER: (1/3)(1/3) = 1/9

(d) The outcome on the first spin can be any of the three regions; the probability of a good outcome is 3/3 = 1. The outcome of the second spin must be the same as the outcome on the first spin -- probability 1/3.

ANSWER: (1)(1/3) = 1/3
