Plain-text version

A and B are two events. B^C is the complement of B. It is known that (i) P(A), the probability of event A, is 1/3 and (ii) P(B^C), the probability of event B^C, is 1/5. Which one of the following statements is certainly true? (A) A and B are independent events. (B) A and B are disjoint (i.e., mutually exclusive) events. (C) A is a subset of B. (D) None of the above
