At a certain college, 6% of all students come from outside the United States. Incoming students there are assigned at random to freshman dorms, where students live in residential clusters of 40 freshmen sharing a common lounge area. How many international students would you expect to find in a typical cluster? With what standard deviation?

Compute P(X) using the binomial probability formula. Then determine whether the normal distriution can be used to estimate this probability. If so, approximate P(X) using the normal distriution and compare the result with exact probability.

A firm reports that 25 percent of its accounts receivable from other business firms are overdue due to economic conditions. If an accountant takes a random sample of seven such accounts, determine the probability of each of the following events by use of the formula for binomial probabilities:

(i) none of the accounts is overdue, and, (ii) exactly two accounts are overdue,

(i) none of the accounts is overdue, and, (ii) exactly two accounts are overdue,

A retailer is receiving a large shipment of media players. In order to determine whether she should accept or reject the shipment, she tests a sample of media players; if she finds at least one defective player, she will reject the entire shipment. If 0.5% of the media players are defective, what is the probability that she will reject the shipment if

a)she tests fifteen media players.

b)she tests thirty media players.

a)she tests fifteen media players.

b)she tests thirty media players.

In an experiment, there are n independent trials. For each trial, there are three outcomes, A, B, and C. For each trial, the probability of outcome A is 0.80; the probability of outcome B is 0.10; and the probability of outcome C is 0.10. Suppose there are 10 trials.

(1) Can we use the binomial experiment model to determine the probability of four outcomes of type A, five of type B, and one of type C? Explain.

a) Yes. Each outcome has a probability of success and failure.

b) No. A binomial probability model applies to only two outcomes per trial.

c) Yes. A binomial probability model applies to three outcomes per trial.

d) No. A binomial probability model applies to only one outcome per trial.

(2) Can we use the binomial experiment model to determine the probability of four outcomes of type A and six outcomes that are not of type A? Explain.

a) Yes. Assign outcome B to "success" and outcomes A and C to "failure."

b) No. A binomial probability model applies to only two outcomes per trial.

c) Yes. Assign outcome C to "success" and outcomes A and B to "failure."

d) Yes. Assign outcome A to "success" and outcomes B and C to "failure."

What is the probability of success on each trial?
