because if you wish to take a combination of a certain number of items, then the order in which you pick them is known as a permutation, not a combination.
for example: if you have 12 people labelled 1 to 12 and you had to pick a team of six, you could choose players 1,2,3,4,5,6 as one of your combinations, but you could also choose them in the order 6,5,4,3,2,1. which ever order you pick them in, you still end up with the same team, thus have the same combination.
the algebraic function nCr is used to determine combinations and is commonly used in binomial distributions.
