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.
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.No | Parameter | Description |
---|---|---|
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)
