PERMUTATIONA function: Description, Usage, Syntax, Examples and Explanation
What is PERMUTATIONA function in Excel?
PERMUTATIONA function is one of Statistical functions in Microsoft Excel that returns the number of permutations for a given number of objects (with repetitions) that can be selected from the total objects.
Syntax of PERMUTATIONA function
PERMUTATIONA(number, number-chosen)
The PERMUTATIONA function syntax has the following arguments:
- Number: An integer that describes the total number of objects.
- Number_chosen: An integer that describes the number of objects in each permutation.
PERMUTATIONA uses the following equation:
Explanation of PERMUTATIONA function
- Both arguments are truncated to integers.
- If numeric arguments are values that are not valid, for example, when the total number is zero (0) and the chosen number is larger than zero (0), PERMUTATIONA returns the #NUM! error value.
- If numeric arguments use data types that are nonnumeric, PERMUTATIONA returns the #VALUE! error value.
Example of PERMUTATIONA function
Steps to follow:
