Quiz 04/06/2011 Name Suppose a discrete random variable X takes the values { 3 , 4 , 5 } with non-zero probability. All other values have zero probability. Assume P ( X = 3) = a , P ( X = 4) = b and P ( X = 5) = c . 1. Write the generating function G X ( t ) of X . 2. Evaluate G X (1). 3. Write the moment generating function
