Main idea: understand the probability of achieving a given number of successes when each trial has the same probability of success.
Binomial_Dist(10,0.5)
This example models the probability of obtaining 0 through 10 successes from 10 independent trials where each trial has a 50% chance of success.
Binomial_Dist(n,p)
n – number of trialsp – probability of success
P(X = k) = C(n,k) p^k (1-p)^(n-k)
The mean is np and the variance is np(1-p).
