Possible values of X, the number of components in a system submitted for repair that must be replaced are 1,2,3, and 4 with corresponding probabilities 0.15, 0.35, 0.35, and 0.15 respectively.

a. Calculate E(X) and then E(5-X)

b. Would the repair facility be better off charging a flat fee of $75 or else the amount $[150/(5-X]?

From the given information, 10.15 2 0.35 3 0.3:5 4 0.15 x p(x) 0.15 0.70 1.05 0.60 Total p(x)= 2.50 a) Calculate the expected

b) 150 Here, we ned to calculate f5-X) r P(x)xp(x) 37.5 0.15 50 0.35 75 0.35 1500.15 Total 5.625 17.50 26.25 22.50 p(x)= 71.8
