PERMUT

Using the Excel PERMUT Function

Summary

The Excel PERMUT function returns the number of permutations for a given number of items. A permutation is any set of values, objects, or events where order is important. This varies from combinations where the order is not significant. The PERMUT function could be used for lottery style probability calculations.

If order is not significant, see the COMBIN function.
