Hayhoe, Leach, Turner, Bruin, and Lawrence (2000) investigated differences between men and women college students with respect to their credit card use. Research participants completed a questionnaire that asked questions about the number of credit cards they had, attitudes toward credit purchases, types of items purchased with credit cards, financial practices, and so on. The table shown below presents a cross-tabulation of the participants€™ gender by number of credit cards they said they had.

a. If you randomly select one of these college students, what is the probability that the student has 0 credit cards given that the student is a male?

b. If you randomly select one of these college students, what is the probability that the student is a female given that the student has 0 credit cards?

c. If you randomly select two students, what is the probability that the second student is a male given that the first student was a female?

d. If you randomly select two students, what is the probability that the second student is a female with 4 or more cards given that the first student was a female with 1-3 credit cards?

e. If you randomly select three students, what is the probability that all three students have 4 or more credit cards?
