Of 40 bank accounts at a small bank, 28 accounts have values of less than $1,000 and the rest have values of at least $1,000. Suppose 5 accounts are randomly sampled (See exercise 9 on page 184 of your textbook for a similar problem.) Question What is the probability that exactly 4 of the 5 accounts have values of at least $1,000? ABC Manufacturing has a policy that it will reject a shipment of parts from its supplier if inspectors find any defective parts in a random sample of 6 parts from the shipment. The supplier has been in business many years and has a long-term defective rate for parts of 5.6%. Question 2 What is the probability that a shipment will be rejected after a given sample of parts is checked?

A manufacturer has determined that a machine averages one faulty unit for every 500 it produces. What is the probability that an order of 300 units will have one or more faulty units?

Show that the probability of drawing a club at random from a standard deck of 52 playing cards is the same as the probability of drawing the ace of hearts at random from a set of four cards consisting of the aces of hearts, diamonds, clubs, and spades.
