Problem 4. (8 points) Consider randomly selecting a student on campus, and let A be the event that the selected student has a VISA card and B be the analogous event for MasterCard. Suppose that P(A)6, P(B)- 4, and P(A n B) 3 (1) (4 points) What is the probability that the selected student has neither type of card? (2) (4 points) What is the probability that the selected student has exactly one of the two types of cards?
