The probability of 
successes in 
trials where 
is the probability of success on any given trial is given by:
\ =\ {{n}\choose{k}}\left(\pi\right)^k\left(1\,-\,\pi\right)^{n\,-\,k})
Where 
is the number of combinations of things taken at a time and is calculated by !})
Arithmetic left as an exercise for the student.
