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) = 0.50, P(B) = 0.35, and P(A N B) = 0.30. Calculate and interpret each of the following probabilities (a Venn diagram might help). (Round your answers to four decimal places.) |A) (b)\PE | A) (d) P(A' | B) (e) Given that the selected individual has at least one card, what is the probability that he or she has a Visa Card?
