Select Does this probability distribution satisfy equation (5.2)? Select d. What is the probability a service call will take three hours?

A technician services mailing machines at companies in the Phoenix area. Depending on the type of malfunction, the service call can take 1, 2, 3, or 4 hours. The different types of malfunctions occur at about the same frequency.

1. Develop a probability distribution for the duration of a service call.
