# PHP | stats_stat_binomial_coef() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP stats_stat_binomial_coef() Function.

The built-in PHP stats_stat_binomial_coef() function returns a binomial coefficient.

## Syntax

Following below is the syntax to use this function -

`float stats_stat_binomial_coef( int \$x, int \$n )`

## Parameter Details

Sr.NoParameterDescription
1

x

The number of chooses from the set

2

n

The number of elements in the set

## Return Value

This built-in function returns the binomial coefficient of n choose x.

## Dependencies

This built-in function was first introduced in statistics extension (PHP version 4.0.0 and PEAR v1.4.0). In this tutorial guide, we used the latest release of stats-2.0.3 (PHP v7.0.0 or newer and PEAR version 1.4.0 or newer).

### Example1

The below example computes the binomial coefficient of 4 choose 0 -

```<?php
var_dump(stats_stat_binomial_coef(0, 4));
?>```

#### Output

When the above code is executed, it will produce the following result -

`float(1)`

### Example2

The below example computes the binomial coefficient of 4 choose 1 -

```<?php
var_dump(stats_stat_binomial_coef(1, 4));
?>```

#### Output

When the above code is executed, it will produce the following result -

`float(4)`
