Use the given moment-generating function, Mx(t), to identify the distribution of the random variable, X in each of the following cases. (Specify the exact type of distribution and the value(s) of any relevant parameters(s): 1. (a) M(-3 (b) M() exp(2e -2) Ce) M T112t)3 (f) Mx(t) = ( 1-3t 10 ) (d) Mx(t)= exp(2t2_t) (e) Mx(t)= - m01 -2t)!

Could anyone help me with the question (d) and (e)? I've finished the question (a), (b) and (c). You don't need to solve the question (a), (b), and (c), and you could use them directly. And the following 2 are (b) and (c). (a) Let (X,M, μ) be a measure space and T : X → y a mapping from X oni at Y Prove thai (i) N (B C y : T-1 (B) EM} is a σ-algebra of subsets...
