b. Draw a graph of the probability distribution.
c. Show that your probability distribution satisfies the conditions required for a discrete
probability function.
d. what is the probability a service call will take three hours?
e. A service call has just come in, but the type of malfunction is unknown. It is 3:00 p.m.
