Consider randomly selecting a student at a Universal University, and let V denote the event that the selected individual has a Visa credit card and M be the analogous event for a MasterCard. Suppose that Pr(V) = 0.5, Pr(M) = 0.4 and Pr(V U M) = 0.25.a) Describe, in terms of V, M and set operations, the event that the selected student has at least one of the two types of credit cards and then calculate its probability.b) Describe, in terms of V, M and set operations, the event that the selected student has neither type of credit card and then calculate its probability. c) Describe, in terms of V, M and set operations, the event that the selected student has a Visa card but not a MasterCard, and then calculate its probability.

a) The event that the selected student has at least one of the two types of credit cards can be…

Question

Consider randomly selecting a student at a Universal University, and let V denote the event that the selected individual has a Visa credit card and M be the analogous event for a MasterCard. Suppose that Pr(V) = 0.5, Pr(M) = 0.4 and Pr(V U M) = 0.25.

a) Describe, in terms of V, M and set operations, the event that the selected student has at least one of the two types of credit cards and then calculate its probability.
b) Describe, in terms of V, M and set operations, the event that the selected student has neither type of credit card and then calculate its probability.
c) Describe, in terms of V, M and set operations, the event that the selected student has a Visa card but not a MasterCard, and then calculate its probability.
