Combinations can be confused with permutations. However, in permutations, the order of the selected items is essential. For example, the arrangements ab and ba are equal in combinations (considered as one arrangement), while in permutations, the arrangements are different.
Combinations are studied in combinatorics but are also used in different disciplines, including mathematics and finance.
