Binomial distribution and Poisson distribution
Calculating P{X = k} involves handling factorials, which is a heavy job (even for computers), and the need for an approximate but quick way to calculate a binomial probability was immediately felt.
Binomial Distribution
Probability Mass Function
The binomial distribution is used when there are exactly two mutually exclusive outcomes of a trial. These outcomes are appropriately labeled "success" and "failure".
Binomial Distribution. The binomial distribution is useful for describing distributions of binomial events, such as the number of males and females in a random sample of companies, ...
Binomial distribution, for the number of "positive occurrences" (e.g. successes, yes votes, etc.) given a fixed number of total occurrences
Multinomial distribution, similar to the binomial distribution, but for counts of multi-way occurrences (e.g.
