Returns the number of permutations for selecting a group of objects (with replacement) from a total number of objects. Learn more.
In Google Sheets, the PERMUTATIONA function is used to calculate the number of permutations for a given number of items taken a certain number at a time, allowing repetitions.
The formula syntax for PERMUTATIONA is:
PERMUTATIONA(number, number_chosen)
number: This is the total number of items or elements available for selection.
number_chosen: This is the number of items to be selected for each permutation.
The function returns the total number of permutations possible, taking into account the repetitions. Note that the order of the selected items matters when calculating permutations.
Here's an example to illustrate how to use the PERMUTATIONA function in Google Sheets:
=PERMUTATIONA(5, 3)
This formula calculates the number of permutations possible when choosing 3 items out of 5 items, allowing repetitions.
The result would be 125, as there are 125 different ways to arrange 3 items out of 5, considering repetitions.
