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.

What is the difference between permutation and combinations?

A permutation is an arrangement of objects in some specific order. Permutations are regarded as ordered elements. A selection in which order is not important is called a combination. Combinations are regarded as sets. For example, if there is a group of 3 different colored balls, then any group of 2 balls selected from it will be considered as a combination, whereas the different arrangements of every combination will be considered as a permutation.
