Problem #2 a.) (7 points) Consider the discrete random variable X that takes on only the three values in Rx = {1,0,+1}withpmf pfl, for x = 1 p{x) = 1p, for x=0 p12, for x = +1 where p is a parameter satisfying 0 :4 p 5 1. Computing the moment generating function MXU): for this random variable. b.) (8 points) A student claims to have computed a moment generating function for some random variable K and he obtained the result, Mr) = 23'\" 1. Explain whf,r this result makes no sense
