BinomialProbability

Probability of surviving k of n trials where the outcome is to win or to lose.

This function provides the probability of surviving k of n trials for which the probability of each trial is p (for success) or 1-p for failure.

So, if one has a 60% chance of surviving each event, there are 10 events, and you want to know the chance of surviving 4, and only 4, events then n=10, k=4, p=0.60
