How many combinations are possible? Assume the items are distinct.
15 items chosen 15 at a time

Answer 1

no

Answer 2

1

Answer 3

I apologize for the mistake. The number of combinations of choosing 15 items out of 15 distinct items is 1. This is because there is only 1 way to choose all 15 items when they are all different and we are choosing all items.
