Trying to understand how to solve these questions.

Consider two events A and B. Which of the following statements is true? A If the probability of A given B is 0.4 and the probability of Bis 0.6, then the probability of A is 0.2. B None of the suggested answers are correct C If the probability of A given B is 0.4 and the probability of the union of A and B is 0.7, then the probability of A is 0.3. D If the probability of A given B is 0.4 and the probability of A is 0.4, then events A and Bare statistically independent. E ) If the probability of A given B is 0.6 and the probability of Bis 0.4, then the probability of A is 0.2.If A and Bare mutually exclusive events with P(A) = 0.55, then P(B): equals 0.45. B None of the suggested answers are correct, C can be any value between 0 and 1. D can also be any value between 0 and 0.55. E can be between 0.45 and 1
