6 over 4, which is equal to (6 x 5 x 4 x 3) / (1 x 2 x 3 x 4).
Four people can be selected from a pool of 8 people in (8 x 7 x 6 x 5) = 1,680 ways.But there are (4 x 3 x 2) = 24 ways to pick the same four people.So you can actually form only 1,680/24 = 70 different 4-person debate teamsfrom a group of 8 students.
The number of ways is 18C5 = 18!/(5!*13!) = 8,568 ways.
There are 8!/(4!*4!) = 70 ways.

If the order doesn't matter (which it probably doesn't, given that we're not selecting the winner, first runner-up, etc. directly), it's slightly trickier: there are 4!, or 24, ways of arranging four items, so we have to divide the larger number by 24 to get 230,300.
