Question

if 'A' is the complement of 'U' then will 'U' be the complement of 'A' ?

U stands for universal set

A is the subset of U

Answer 1

Hi Nitin!

If U is the universal set and A ⊂ U such that A = U’ then A = Φ

Where, Φ stands for the null set.

Also, Φ = U’ and U = Φ’

Thus, if A = U’ then U = A’
