What is the difference between the permutations rule and the combinations rule? Choose the correct answer below. A. The permutations rule takes order into account, whereas the combinations rule does not. B. The permutations rule takes replacement into account, whereas the combinations rule does not. C. The combinations rule takes replacement into account, whereas the permutations rule does not. D. The combinations rule takes order into account, whereas the permutations rule does not.

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)!
