A circle has random points on its circumferance. How many ways can you form a quadrilateral, a triangle, and a octagon using these points?
I have no idea how to get an numerical answers for this question without using n to represent the number of points on the circle. Thanks.

I think using 'n' is fine...just make a correct formula such that for any n you can get a specific answer.

Of course you need n.
In how many ways can you choose the vertices of an r sided polygon from n points ?
