a) M(t) = (1/8)*(1+exp(t))^3 b) M(t) = exp(4t^2) c) M(t) = (exp(2e^t))/(exp(2)) d) M(t) = 8/(2-t)^3 I'm having trouble with these. Do I integrate the M(t) to get the probability density function?

Do I integrate the M(t) to get the probability density function? No, you're meant to compare them against a table of moment generating functions of well known distributions (discrete and continuous) ....
