comment Generating Function for Recurrence Relation in 2 Variable
@Henry The recurrence relation that I am trying to solve is actually more complex than the one mentioned in my question. Which is why I am looking for the steps I can take to solve similar questions.

comment Generating Function and Mean
@ShreevatsaR I generated the series using a 2D matrix for S(n,k) and calculated the values. It was forming a series. The nth term of the series was $G'_n(1) = \frac{2 \cdot n}{3}$

comment Generating Function and Mean
Yes thats exactly where I understood the question wrong. My only problem now is, How do I compute $G_n(z),\ G_n'(z)\ and \ G_n''(z)$ . I already know $G′n(1)$.

@the_candyman: Edited the question. Although ShreevastsaR caught what I was looking for before I could finish my edit.

comment probability of sum of a given set of whole numbers being greater than a certain number
Problem sounds exactly like the one in an ongoing contest : codechef.com/AUG13/problems/SHIRO And looking at your other questions, I am very sure its from the contest.

@CalvinLin : Thats what i tried to do with that recurrence relation. Enumerate all k subset. F(i,x,k) is the probability of getting k heads, given x heads have already occurred till coin i.

comment Probability of getting 'k' heads with 'n' coins
I came up with some thing like F(i, x, k) = Pi * F(i+1, x+1, k) +f(i+1, x, k) for all i from 1 to n-k and F(i,k,k) = Pi
