What is combination in math?
Both "COMBIN" and "nCr" here redirect. See Combination (disambiguation) and NCR for further usage (disambiguation).
A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant (unlike permutations). Three fruits, such as an apple, an orange, and a pear, for instance, can be combined into three different pairs: an apple and a pear, an apple and an orange, or a pear and an orange. A k-combination of a set S is officially defined as a subset of S's k unique members. So, if and only if each combination has the same elements, two combinations are said to be identical.
