a. Explanation The given information is that P ( A ) = 0.40 , P ( B ) = 0.50 and P ( A ∩ B ) = 0.05 . Conditional probability: The conditional probability is defined as the probability of event A given that B has occurred. It can be denoted as P ( A | B ) . The conditional probability is calculated as follows. P ( A | B ) = P ( A ∩ B ) P ( B ) b. To determine Check whether A and B are independent or not.
