33) True or False: If the conditional probability of an event A given another event B is same as the marginal probability of the event A, then events A and B are mutually exclusive. False – as I just said, if P(A | B) = P(A), that means that A and B are independent…that doesn’t mean that A and B are mutually exclusive. Remember: if A and B are mutually exclusive, then if one happens, the other can’t…in other words, P(A and B) = 0. 34) If the occurrence or non-occurrence of one event does not affect the occurrence or non-occurrence of another
event, the two events are ________________________.
