I am asked to prove the following distribution equal to 1. The distribution is obtained by using classic Binomial distribution and apply stirling approximation.

2. Relevant equations

P(X) = [tex]\frac{1}{\sqrt{Nx(1-x)}}[/tex]exp(-NI(x))

where I(x) = x ln (x/p) + (1-x) ln (1-x/1-p)

This form seems complicated to me. Any suggest for the first step to simplify the proof??
