Question

Let U={2, 4,6,8} and A={6, 8}, then fill in the blanks A'=
A U A' = A n A' =
A U ¢ =

Answer 1

Explanation:

(i) It can be clearly seen from the Venn diagram that

A∪A′=U

(ii) ϕ′∩A=U∩A=A

∴ϕ′∩A=A

(iii) It can be clearly seen from the Venn diagram , there is no common portion between A and A' .

Hence, A∩A′=ϕ

(iv) U′∩A=ϕ∩A=ϕ

∴U′∩A=ϕ
