Suppose the events B1, B2, and B3 are mutually exclusive and complementary events, such that P1B12 = .2, P1B22 = .15, and P1B32 = .65. Consider another event A such that P1A2 = .4. If A is independent of B1, B2, and B3, use Bayes’s Rule to show that P1B1  A2 = P1B12 = .2. Applying the Concepts—Basic
