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) = 0.5, and P(A n B) = 0.15.
(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 ? B).
(b) What is the probability that the selected individual has neither type of card?
c) Describe, in terms of A and B, the event that the selected student has a Visa card but not a MasterCard.
A' n B
A' n B'
A' ? B'
A ? B'
A n B'
Calculate the probability of this event.
