Question
![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, 0.15, 0.35, and 0.35, respectively.
(a) Calculate E(X) and then E(5 – X).
E(X)
=
E(5 - X)
(b) Would the repair facility be better off charging a flat fee of $95 or else the amount $
150
?
[(5 - X)]
Note: It is not generally true that E.
E(Y)
