1 # Complement 2 3 L1 4 5 **Definition:** The complement of a set is the set of all elements not in the original set, but in the consideration space (often sample space). 6 7 There are technically two types of complements the absolute and relative complements. Generally we are talking about the relative complement which is the set defined as the difference between the superset and the subset. The absolute complement uses the U set ([UniversalSet](UniversalSet.md)) as the superset.
