Distance learning. A study of the students taking distance
learning courses at a university finds that they are mostly older
students not living in the university town. Choose a distance
learning student at random. Let A be the event that the student is
25 years old or older and B the event that the student is local.
The study finds that P(A) = 0.7, P(B) = 0.25, and P(A and B) =
0.05.
(a) Make a Venn diagram showing the events: {A and B}, {A and not
B}, {B and not A}, and {neither A nor B}.
(b) Describe each of these events in words.
(c) Find the probabilities of all four events and add the
probabilities to your Venn diagram.

5. 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. Suppose that P(A) = 0.5, P(B) = 0.4, P(A∩B) = 0.25. Calculate and interpret the following probabilities (a Venn diagram may help). (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...
