(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A random variable X has probability generating function g_{X}(s) = (5-4s^{2})^{-1}

Calculate P(X=3) and P(X=4)

2. Relevant equations

3. The attempt at a solution

Ehh don't really know where to go with one... I know:

g_{X}(s) = E(s^{x}) = Ʃ p(X=k)(s^{k})

Nit sure how to proceed..

Any help would be great!!

Regards

Tam
