Bernoulli binomial probability formula
$$P_{n}\cdot (k) = C_{n}^{k}\cdot p^{k}\cdot q^{(n-k)}$$
k - number of successes
n - number of trials
p - probability of success in one trial
q = 1 - p - probability of failure in one trial
n - number of trials
p - probability of success in one trial
q = 1 - p - probability of failure in one trial
Find
It is known that:
