Statistical - PERMUT Function

Description

The PERMUT function returns the number of permutations for a given number of objects that can be selected from number objects. A permutation is any set or subset of objects or events where internal order is significant. Permutations are different from combinations, for which the internal order is not significant.

Syntax

PERMUT (number, number_chosen)

Arguments

Argument	Description	Required/ Optional
Number	An integer that describes the number of objects.	Required
Number_chosen	An integer that describes the number of objects in each permutation.	Required

Notes

The equation for the number of permutations is −

$$P_{k,n}=\frac{n!}{\left ( n-k \right )!}$$
Both arguments are truncated to integers.
If number or number_chosen is nonnumeric, PERMUT returns the #VALUE! error value.
If number ≤ 0 or if number_chosen < 0, PERMUT returns the #NUM! error value.
If number < number_chosen, PERMUT returns the #NUM! error value.

Applicability

Excel 2007, Excel 2010, Excel 2013, Excel 2016
