A. The permutations rule takes order into account, whereas the combinations rule does not.

Step-by-step explanation:

Permutation is an orderly form of combination. They both deal with numbers an element can be arranged in different ways.

The main difference is that permutation takes into account the order in which the arrangement takes place while combination doesn't take that into account.

Combination formula: nCr = n! / r! * (n - r) !

Permutation formula: P (n, r) = n! (n-r) !
