Tutu Tableware prides itself on the fact that 1 percent or less of its merchandise is defective. They are so confident of their record, they offer extra discount if defective ever exceed 3 in a shipment of 100 sets. Last week they sent out a shipment of 200 sets. Their customer claimed that the shipment contained
15 defective and demanded the discount. What is the probability that the customer's claim is true?
