Consider randomly selecting a student at a certain university, and let A denote the event that the selected individual has a Visa credit card and B be the analogous event for a MasterCard. Suppose that P(A) = 0.6, P(B) = 0.2, and P(A n B) = 0.05. (a) Compute the probability that the selected individual has at least one of the two types of cards (i.e., the probability of the event A UB). 0.65 x (b) What is the probability that the selected individual has neither type of card? 0.35 (c) Describe, in terms of A and B, the event that the selected student has a Visa card but not a MasterCard.
