PPT-Probabilities of Disjoint and overlapping events

Unions and Intersections When you consider all the outcomes for either of two events A and B you form the union of A and B When you consider only the outcomes shared by both A and B you form the . For example let be the probability that a die roll is even and be the probability that a die roll is greater than 3 We have the following sets to describe each event The probability that the joint event occurs is the probability that the outcome is St. .
