1. ## simple question - the last on my assignment! PLEASE :)))

Here is the question:for t>0 express the probability generating function in terms of moment generating function when it exists.
I got it this way:
g(t)=E[t^x)=E[exp{xlogt}]=M(log t)

Where g(t) is pgf and M(log t) is mgf

Does that make any sense whatsoever?

Thank you
