A sample space contains six sample points and events A, B, and C, as shown in the Venn diagram below. The probabilities of the sample points are P112 = .20, P122 = .05, P132 = .30, P142 = .10, P152 = .10, and P162 = .25.

a. Which pairs of events, if any, are mutually exclusive?
Why?

b. Which pairs of events, if any, are independent?
Why?

c. Find P1A ∪ B2 by adding the probabilities of the sample points and then by using the additive rule.
Verify that the answers agree. Repeat for P1A ∪ C2.
