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 0.45, 0.05, 0.45, and 0.05, respectively. (a) Calculate E(X) and then E(5 – X). E(X) = E(5 – X) = 15U (b) Would the repair facility be better off charging a flat fee of $65 or else the amount $ the amount = ( 1590;} [note: It is not generally true that e( 9 - men ?
