COMBIN

Description

The COMBIN function finds the number of different ways you can combine a number of items into groups of a specific size, ignoring the order within the groups.

Syntax

COMBIN(items, size)

• items: The total number of items that can be combined.
• size: The number of items combined in each group.

Note: Remember that combinations are not the same as permutations. The order of the items in a group is ignored for combinations but not for permutations. For example, (1, 2, 3) and (3, 2, 1) are the same combination but two unique permutations.
