Through a purchase card tracking system, a local supermarket is able to determine who shopped at their store during any given day. The store is popular, attracting a steady stream of customers. At the end of each day, store personnel call 10 customers to find out about their shopping experience. There are two categories of customers: those with no complaints and those with complaints. Any customer who has a complaint, such as not being able to find a particular product or having to wait too long in line, is considered a defective for the store. The store tracks this information and uses it to improve store operations. While striving for perfection, the store managers realize that it isn't possible to make everyone happy. In the past, the probability of a customer with a complaint is 0.003. Calculate the probability that on any evening, two or fewer customers have complaints. |
