--------------------------------------------------------------------------

You just have the answer: 8C3.

Do you know what is it?

It is the number of combinations 8 objects taken 3 at a time:

8C3 = %288%2A7%2A6%29%2F%281%2A2%2A3%29 = 8*7 = 56.

Regarding the combinations, read the lesson Introduction to Combinations in this site.
