Assume that we have two events, A and a, that are mutually exclusive. Assume further that we know P\") = 0.9 and P(B) = 0.2. a. what is P(A n a)? b. what is P(A l B)? ) equal to Pm? Are evenls A and E dependent or independent? d. A student in statistics argues that the concepts of mutually exclusive events and independent events are really the same, and that if evens are mutually exclusive they must be independent, ls this statement accurate? Use the probability inlonnation in this problem to justify your answer. what general conclusion would you make about mutually exclusive and independent evens given the results or this
