The billing department of a local department store sends monthly statements to the store’s customers. For those statements to reach the customer in a timely fashion, the addresses on the envelopes must be correct. Occasionally errors are made with the addresses. The billing department estimates that errors are made 2 percent of the time. For this continuous process, in which an error in the address is considered a nonconforming unit, what is the probability that in a sample size of eight, one address or less will be incorrect?
