- In mathematics, two sets that have no element in common. Equivalently, two disjoint sets are sets whose intersection is the empty set. For example,
*{1, 2, 3}*and*{4, 5, 6}*are disjoint sets, while*{1, 2, 3}*and*{3, 4, 5}*are not disjoint. A collection of two or more sets is called disjoint if any two distinct sets of the collection are disjoint. ← Wikipedia
