Suppose a random excitement has a sample space of {a, b, c, d, e}. The probabilities of ‘a’ , ‘b’ , ‘c’ , ‘d’ and ‘e’ are 0.1, 0.15, 0.3, 0.25 and 0.2, respectively. Let A = {a, c, e}, B = {a, b} and C = {b, c, d}. Which of the following is incorrect? A) P(B’) = 0.75 B) P(A ∩ C)=0.3 C) Events A and C are exhaustive but not disjoint D) None of the above
