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.
