WebApr 12, 2024 · To sample without replacement is handled by what is referred to as the hypergeometric distribution. However, as long as the population size is much larger (20 x or more) than the sample size, we can use the binomial distribution. In this instance, we would be approximating the hypergeometric distribution with the binomial distribution. Summary

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.
