A dry cleaning company has done some research into how customers rate its services, and whether the customer will use its services again. The data are summarized in Exhibit 4.18.

What is the probability that a customer will use the dry cleaning company’s services again? What is the probability that a customer who rates the services as “good” or “excellent” will not use the services again? What does this indicate? Are the service rating and the tendency to use the services again independent?
