Question

How many ways are there to select 3 candidates from 8 equally?

Answer 1

If order matters, there are 8·7·6 = 336 ways to select 3 from 8.

If order doesn't matter, that number is divided by the number of ways you can arrange 3 items, which is 6.

... 336/6 = 56 . . . . if order doesn't matter
