Binomial distribution

Statistics.

A discrete probability distribution built up from a series of binomial trials.

The binomial distribution can be a useful model for processes where:

1. The process consists of a whole number of identical trials or situations (n).
2. Each trial results in just one of only two possible outcomes (eg success or failure).
3. The probability of success (p) remains constant for each trial.
4. The trials are independent and
5. Primary interest lies in the probability of a specified number of successes (or of failures) in the n trials.
