Binomial distribution with replacement
WebThe concept of hypergeometric distribution is important because it provides an accurate way of determining the probabilities when the number of trials is not very large and when samples belong to a finite population without replacement. The hypergeometric distribution is analogous to the binomial distribution Binomial Distribution The … WebIn probability theory and statistics, the negative binomial distribution is a discrete probability distribution that models the number of failures in a sequence of independent and identically distributed Bernoulli trials before a specified (non-random) number of successes (denoted ) occurs. For example, we can define rolling a 6 on a dice as a …

Consider a box of N tickets of which G are labeled "1" and N − G are labeled "0." The sample sum of the labels on n tickets drawn at random with replacement from the box has a binomial distribution with parameters n and p = G / N ; the probability that the sample sum equals ...
