RANDOM  VARIABLES                            [CHAP  2



                 where a ( > 0) and k are constants.
                 (a)  Find the value of k.
                (b)  Find the cdf of X.
                 (c)  Find the mean and the variance of X.
                 Ans.  (a)  k = a/z   (b)  F,(x)  =

                     (c)  E(X) = 0, Var(X) does not exist.
