variance (binomial distribution)

$$\sigma^2=npq$$

applications for binomial/multinomial

multinomial distribution

hypergeometric distribution

acceptance sampling

binomial vs hypergeometric

differences in sampling

-binomial requires independent processes WITH replacement

-hypergeometric does not require independence and WITHOUT replacement

negative binomial distribution

geometric distribution

poisson distribution
