Problem 5. (10 points) Steve sells cars at a local dealership. The number, X, of cars he sells on a given day is uncertain, but an estimate of the probability distribution for X is: Cars sold Probability 0.2 0.45 0.25 0.2 0.45 0.25 (b) Steve earns both a salary and a commission for selling cars so that his total earnings, Z, for the day are given by the following linear formula: 2-50 + 200X Find the mean of Z, which represents Steve's average daily earnings
