# Thread: Identify the corresponding distributions to the following moment generating functions

1. ## Identify the corresponding distributions to the following moment generating functions

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?

No, you're meant to compare them against a table of moment generating functions of well known distributions (discrete and continuous) ....
