In other words, mutually exclusive events cannot both occur at thesame time, which means they have no sample points in common.3.39.The union of two events A and B is the event that occurs if either A or B (or both) occurs on a singleperformance of the experiment.3.40.The intersection of two points A and B is the event that both A and B occur on a single performanceof the experiment.3.41.The complement of an event A is the event that A does not occur. It is the event consisting of all thesample points that are not in event A. We denote the complement of A by Ac3.42.The rule of complements states that the sum of the probabilities of complementary events equals 1.3.43.The additive rule of probability for mutually exclusive events states that if two events A and B are.
