Consider a discrete random variable X with z-transform: F(2) = e²e+2-z Find the probabilities P[X = 0], P[X = 1], P[X = 2], P[X = 3] and P[X = 4]. What do you suppose is the probability P[X = k] for any k? Also find E[X]. [Hint: e² may be expanded as e² = 1+z+z²/2!+ z³/3! + ....] Consider a discrete random variable X with z-transform: F(2) = e²e+2-z Find the probabilities P[X = 0], P[X = 1], P[X = 2], P[X = 3] and P[X = 4].
