Question Answered step-by-step (a) Suppose Y1 is a gamma random variable with parameters 1 and and… (a) Suppose Y1 is a gamma random variable with parameters ?1 and ? and Y2 is also a gamma random variable with parameters ?2 and ?. Assuming Y1 and Y2 are independent, use the moment generating function to find the density function of U = Y1 + Y2. (b) Suppose Y1, Y2, . . . , Yn are Poisson random variables each with parameter ?. Assuming Y1 and Y2 are independent, use the moment generating function to find the probability function for W = Y1+Y2+· · ·+Yn.
