Question 13 Students who live on campus and purchase a meal plan are randomly assigned to one of three dining halls: the Commons, Northeast, and Frazier. What is the probability that the next student to purchase a meal plan will be assigned to the Commons?0.330.50.660.25

Question 14 An inventory of appliances contains four white washers and one black washer. If a customer selects one at random, what is the probability that the black washer will be selected?

Question 15 Three events occur with probabilities P(E1) =0.35, P(E2) =0.15, P(E3) =0.40. If the event occurs, the probability becomes P(E1|B) =0.25, P(B) =0.30. Calculate P(E1and BB).

Question 16 The method of probability assessment that relies on an examination of historical data from similar situations is:

Question 17 Drake Marketing and Promotions has randomly surveyed 200 men who watch professional sports. The men were separated according to their educational level (college degree or not) and whether they preferred the NBA or the National Football League (NFL).

Question 18 When a customer enters a store there are three outcomes that can occur: buy nothing, buy a small amount, or buy a large amount. In this situation, if a customer buys a large amount, he or she cannot also buy a small amount or buy nothing. Thus the events are:

Question 19 Of the last 100 customers entering a computer shop, 25 have purchased a computer. If the classical probability assessment for computing probability is used, the probability that the next customer will purchase a computer is:
