Complement of a set, Law of Complement, Property of Complement

Let U be the universal set and A is a subset of U. Then the complement of A is the set of all elements of U which are not the elements of A.

Symbolically, we use A' or Ac to denote the complement of A with respect to U.

 A' = {x∶ x ∈ U and x ∉ A }. Obviously, A' = U – A 

 

 

Properties of Compliment

  • A ∪ A′ = U

  • A ∩ A′ = φ

  • (A' )' = A

  • U′ = φ and φ′ = U

  • A - B = A ∩ B'
