Intersection of Sets

Intersection of Sets

Consider two sets A and B in a universal set U. The intersection of sets A and B is the set of elements in U that simultaneously belong to A and B.

The intersection of A and B refers to both the operation and the result of this operation, which is the set of elements common to A and B.


The symbol used is: “∩”, which is read as “inter” or “intersection”.

Therefore, A ∩ B is read as “A inter B” or “set A intersection set B“.


In this representation, set E ∩ F = {c, d, e} and E ∩ G = {d, e, f, g}.
