Answer 3

The "C" stands for "combination." Suppose you had 10 distinct objects (such as 10 distinct foreign coins), and that you want to know how many possible combinations you could make from these 10, taken 7 at a time.

The formula for C is \[_{n}C _{x}=\frac{ n! }{ x!(n-x)! }\]

@jzellem1004: great of you to want to help. However...you don't seem to have read the Code of Conduct. Would you do that now and see what it has to say about doing the work of others for them and providing them with answers. Please stop now, while you're ahead, and stop asking for medals also. Thank you.
