Find the pmfs corresponding to the following mgfs defined for a discrete random variable. Write your solutions in the form Pi y = y1 P2 y = Y2 p(y) = {: : Pk y = Yk 0 o therwise or in the form some formula y E Y p(y) otherwise for a set y to be identified, or identify the distribution by name with any parameters identified. If the function is NOT the mgf of a discrete pmf, state this and explain why.
