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) = 0.55, P(B) = 0.40, and P(An B) = 0.20. Calculate and interpret each of the following probabilities (a Venn diagram might help). (Round your answers to four decimal places.) (a) P(BIA) (b) P(B¹A) (c) P(A|B) (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?

the following probabilities (a Venn diagram might help). (Round your answers to four decimal places.)
(a) P(B|A)
(b) P(B'| A)
(c) P(A|B)
(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?
