<h3><u>What is a combination?</u></h3>
A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations).
For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear; an apple and an orange; or a pear and an orange. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members.
