Distribution of Random hyperharmonic series
The random hyperharmonic series is the infinite series S = Sum(1,inf,d(i)/i^pow), where integer pow is greater than 1, and d(i) are independent, identically distributed random variables with property P(d(i)=0) = P(d(i)=1) = 0.5. Cumulative function F(x) = P(S < x) for even powers can be build by combination of analytical and numerical computations.
