    I need some real serious help. This is the problem I need to finish.

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

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

    The problem I am having is what to do after I get the probability outcome. I am at a total lost.

    Hi NIkNice,

    The solution is almost given in the problem. You have X=1,2,3, or 4, and they each have the same probability. The probabilities add up to 1...

    This is exactly like the probability of the different outcomes when you roll a single die.....each outcome =1/6 and their sum =1
