2. Binomial formulas
The number of ways of arranging k successes among n observations is given by the binomial coefficient

3. Binomial probability
If X has the binomial distribution with n observations and probability p of success on each observation, the possible values of X are 0, 1, 2, N. If k is any one of these values.

Oh by the way – the previous formula is on the calculator.

5. Binomial mean and standard deviation
If a count X has the binomial distribution with number of observations n and probability of success p, the mean and standard deviation of X are
