Binomial distribution chart
X : a random variable following a binomial distribution
n : number of trials
p : probability of success for each trial (number between 0 and 1)
P(X = k) : probability of getting exactly k successes in n trials
`P(X = k) = ([n], [k]) * p^k*(1-p)^k`
where `([n], [k])` is the binomial coefficient also called 'n choose k',
`([n], [k]) = (n!)/(k! * (n-k)!)`
