Dear experts,

I want to extract the coefficient of z^k from an infinite series summation (known as probability generating function or characteristic function or Z-transformation) , the co-efficient is actually the probability of the R.V. will take value k.

Next problem in the same question is the summation is not working if I sum from 0 to infinity. It is working from 0 to 300.

I have attached the PDF for expressing the problem and the Maple code. I have used convert(.., FormalPowerSeries,.. );
