    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) ....
