(a) ( 3 points) Show that the probability generating function of the binomial random variable XB(4,32) is GX(z)=(32z+1)4,forz>0. (b) (3 points) Derive the probability generating function of the Poisson random variable YPo() where >0. (c) It is given that a non-negative integer-valued random variable Z has the following probability generating function: GZ(z)=[3(2z+1)ez1]4,forz>0 (i) (2 points) Find Pr(Z=0). (ii) (4 points) Find Pr(Z
