suggested that during a given year 86% of these computers needed no repairs, 9% needed to be repaired once, 4% twice, 1%
three times, and none required more than three repairs.
-The service contract for the printer estimates a mean annual cost of $120 with standard
deviation of $30. What is the expected value and standard deviation of the total cost for the
service contracts on computer and printer?
