'''Expected Number of Xelima Stones needed per Weapon Upgrade'''
Taking into account that the expected number of attempts before success is 1/(probability of success), These formula's that I've used...
Probability of success from n-1 to n: P(n) (given above)
Expected number of Xelima Stones needed from +n-1 to +n: E(n)=1/P(n) for n=1,2,3; E(n)=[(1/P(n)) - 1]*E(n-1) +1 for n>3
Expected number of Xelima Stones needed from +0 to +n: T(n) = E(1)+E(2)+...E(n)
