    find pmf by using mgf




    hi!
    I have problem to solve the question below..did i need to use Poisson distribution to solve this question or maybe not??

    Find the probability mass function of Y if its moment generating function is M(t)=exp^(lamda(exp^(t)-1)+3t),for lamda>0.

    Do you know to transform the Moment Generating Function to its corresponding Probability Generating function?

    Hints: e^{\ln t} = t

    Once you obtain the PGF then you can obtain the corresponding pmf.
