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 where P(A) = 0.45, P(B) = 0.40, and P(AB) = 0.20. Calculate and interpret each of the following probabilities (a Venn diagram might help). (Round your answers to four decimal places.) (b) P(B' | A) 0.5555 (c) P(AB) 0.5 (d) P(A' | B) 0.4285 X x X (e) Given that the selected individual has at least one card, what is the probability that he or she has a Visa Card? 0.9166 X
