In probability theory and statistics, the binomial distribution is the discrete probability distribution which gives only two possible results in an experiment, either Success or Failure.For example, if we toss a coin, there could be only two possible outcomes: heads or tails, and if any test is taken, then there could be only two results: pass or fail.Dec 06, 2020 · The Poisson distribution is used when it is desired to determine the probability of the number of occurrences on a per-unit basis, for instance, per-unit time, per-unit area, per-unit volume etc. In other words, the Poisson distribution is the probability distribution that results from a Poisson experiment.
As a general rule, the binomial distribution should not be applied to observations from a simple random sample (SRS) unless the population size is at least 10 times larger than the sample size. To find probabilities from a binomial distribution, one may either calculate them directly, use a binomial table, or use a computer.
