Probability: Moment Generating Functions and Poisson Process
Let X be a discrete random variable with probability mass function Pr {X=k} = c(1+ k^2) for k= -2, -1, 0, 1, 2.a) Determine c.b) Determine Pr {X <= 0}c) Determine the mean of Xd) Why is the previous answer fairly obvious?e) Determine the variance of Xf) Compute Pr {X=2 | X >= 0}g) Determine the moment generating function of X
Let Y be a Poisson random variable with parameter 1.5a) Compute Pr {Y=0}b) Compute Pr {Y <= 1}c) Compute Pr {Y=0 |Y <= 1}d) What is E[Y]?e) Determine the variance of Yf) Determine the moment generating function
