Considerations when using the COMBIN function
Numeric arguments are truncated to integers.
If either argument is nonnumeric, COMBIN returns the #VALUE! error value.
If number < 0, number_chosen < 0, or number < number_chosen, COMBIN returns the #NUM! error value.
A combination is any set or subset of items, regardless of their internal order. Combinations are distinct from permutations, for which the internal order is significant.
