evaluate the combination:
there is a set of parentheses, 15 on top of a 15- it would look like this, just one set of parentheses
(15)
(15)
i am just stuck
This is the notation used for combinations. In particular, its top-choose-bottom. In your example, you have 15 items (top) and you want to determine the number of ways of picking 15 of them (bottom).
BTW, the answer in this example is 1.
