In mathematics, a combination refers to the selection of items from a larger set without considering the order in which they are selected. Essentially, combinations are subsets of items from a larger group where the order doesn't matter.
For example, if you have a set of three letters {A, B, C}, the combinations of selecting two letters from this set would be {AB, AC, BC}. Notice that {AB} and {BA} represent the same combination because the order doesn't matter.
Combinations are widely used in various areas of mathematics, statistics, and computer science, particularly in counting and probability problems. They are essential for determining the number of possible outcomes in scenarios where order doesn't matter, such as selecting a team from a group of people or choosing a subset of elements from a set.
