Suppose X Poisson(), where > 0 is the mean parameter of X, and Y is

Fantastic news! We've Found the answer you've been seeking!

Question:

Suppose X ∼ Poisson(λ), where λ > 0 is the mean parameter of X, and Y is a Bernoulli random variable with P[Y =1]=p and P[Y=0]=1−p.

(a) Calculate the moment generating function of Y .

(b) Assuming X and Y are independent, find the moment generating function of Z = X + Y . By differentiating the moment generating function of Z an appropriate number of times , find the mean and variance of Z.

(d) Determine the probability mass function of the conditional distribution X|Z = z.
