Prove the law of double complements for sets:
If AA is a set and A∁A∁ is its complement than prove that:
(A∁)∁=A(A∁)∁=A
I started with:
A∁=U−AA∁=U−A
where U is the universal set.
If AA is a set and A∁A∁ is its complement than prove that:
(A∁)∁=A(A∁)∁=A
I started with:
A∁=U−AA∁=U−A
where U is the universal set.
