. Two events, A and B, are statistically dependent. P(A) = 0.4, P(B) = 0.2, and P(A or B) = 0.5. Find the probability that: a. both A and B will occur; b. neither A nor B will occur; c. A will occur, given that B has occurred; and d. B will occur, given that A has occurred. a) P(A and B) = b) P(neither A nor B) = 1 - P(A or B) c) P(A B) = P(A and B) / P(B) d) P(BA) =
