1—Bernoulli Distribution
Success and failure for identical, repeated trials that have a constant probability.
2—Binomial Distribution
Total number of successes in n Bernoulli trials
3—Multinomial Distribution
Joint distribution of n independent trials, each with k outcomes
4—Hypergeometric Distribution
The total number of successes in n trials w/o replacement from K successes and N-K failures.
5—Geometric Distribution
The # of the Bernoulli trial for the first success.
6—Negative Binomial Distribution
The # of the Bernoulli trial for the rth success.
7—Poisson Distribution
Look for a rate (lambda) per hour. Adjust if not per hour.
8—Discrete Uniform Distribution
Constant probability over the integers [a,b].
9—Continuous Uniform Distribution
Constant density on (a,b).
10—Exponential
Time until first occurrence of a Poisson.
11—Gamma Distribution
