What Is Combination In Math?
An arrangement of objects in which the order is not important is called a combination. This is different from permutation where the order matters. For example, suppose we are arranging the letters A, B and C. In a permutation, the arrangement ABC and ACB are different. But, in a combination, the arrangements ABC and ACB are the same because the order is not important.
What Is The Combination Formula?
The number of combinations of n things taken r at a time is written as C(n, r).
The following diagram shows the formula for combination. Scroll down the page for more examples and solutions on how to use the combination formula.
