Properties Hypergeometric Probability Distribution

The random variable x the number of items from the group of interest. Finite population n 5 of trial n fixed number of trials.

In probability theory and statistics the hypergeometric distribution is a discrete probability distribution that describes the probability of displaystyle k successes random draws for which the object drawn has a specified feature in displaystyle n draws without replacement from a finite population of size.

Properties hypergeometric probability distribution. M 1 m read as m factorial. Properties of the hypergeometric distribution the hypergeometric distribution is a discrete probability distribution applied in statistics to calculate proportion of success in a finite population and. 1 2 3.

The outcomes of a hypergeometric experiment fit a hypergeometric probability distribution. Mm m read as m choose m. In what follows we will use the mathematical formula for combinations given by m m m.

Discrete probability distributions alexander katz christopher williams and jimin khim contributed the hypergeometric distribution intuitively is the probability distribution of the number of red marbles drawn from a set of red and blue marbles without replacement of the marbles. The hypergeometric probability distribution is used in situations where items are selected and not replaced. Hypergeometric distribution a discrete random variable x is said to have a hypergeometric distribution if its probability density function is defined as where n is a positive integer m is a non negative integer that is at most n and n is the positive integer that at most m.

The distribution of x is denoted x h r b n where r the size of the group of interest first group b the size of the second group and n the size of the chosen sample.
