# stats_dens_pmf_hypergeometric

(PECL stats >= 1.0.0)

stats_dens_pmf_hypergeometricProbability mass function of the hypergeometric distribution

### Descripción

stats_dens_pmf_hypergeometric(
float `\$n1`,
float `\$n2`,
float `\$N1`,
float `\$N2`
): float

Returns the probability mass at `n1`, where the random variable follows the hypergeometric distribution of which the number of failure is `n2`, the number of success samples is `N1`, and the number of failure samples is `N2`.

### Parámetros

`n1`

The number of success, at which the probability mass is calculated

`n2`

The number of failure of the distribution

`N1`

The number of success samples of the distribution

`N2`

The number of failure samples of the distribution

### Valores devueltos

The probability mass at `n1` or `false` for failure.

`You can use this method to work out lottery odds:/*** N is the population size OR total balls in the lottery draw* K is the number of success states in the population OR the number of correct balls drawn from the pool* n is the number of draws OR the number of times we draw from the pool to get the winning numbers.*/\$N = 49; //Total balls in the pool\$K = 1; //Successful matches to win\$method = new Hypergeometric(\$N, \$K, \$K);\$odds = \$method->pmf(\$K); return 1/\$odds;//Will return 49`
