What is a disjoint sets, definitions, and examples

Disjoint sets are sets whose intersections are empty. If no member of set Q belongs to another set P then the two sets are disjoint. In general disjoint sets do not intersect.

How to find disjoint sets

Disjoint sets can be easily understood using examples. Let’s look at some examples under disjoint sets. If set A={1,3,5,7,9} and set B={2,4,6,8,10}. Set A and B are disjoint sets since they both do not have members in common.

If set Q={1,5,7} and P={4,6}, the intersection of set Q and P is empty i.e Q ∩ P =∅. Similarly, set A={3,7,9} and B={2,8,10} are disjoint sets since no member belongs to set A and B i.e A ∩ B = ∅.

Disjoint sets are said to be mutually exclusive. In the Venn diagram below set X and Y are disjoint sets since there is no Intersection for the two sets.
