"In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability ). A single success/failure experiment is also called a Bernoulli trial o… " - Binomial without replacement

Binomial without replacement

WebHypergeometric and Negative Binomial Distributions The hypergeometric and negative binomial distributions are both related to repeated trials as the binomial distribution. When sampling without replacement from a finite sample of size n from a dichotomous (S–F) population with the population size N, the hypergeometric distribution is the WebA Binomial Distribution describes the probability of an event with only 2 possible outcomes. For example, Heads or Tails. It can also be used to describe the probability of a series of independent events that only have 2 possible outcomes occurring. For example: Flipping a coin 10 times and having it land with 5 on heads exactly 5 times.
