यदि \(U=\mathbb{R}\), (A=\(-\infty,0]\) और \(B=[2,\infty\)), तो \(A' \cap B'\) क्या है?
If \(U=\mathbb{R}\), (A=\(-\infty,0]\), and \(B=[2,\infty\)), what is \(A' \cap B'\)?
Explanation opens after your attempt
Correct Answer
A. ((0,2))
Concept
(A'=\(0,\infty\)) and (B'=\(-\infty,2\)). Their intersection is ((0,2)).
Why this answer is correct
The correct answer is A. ((0,2)). (A'=\(0,\infty\)) and (B'=\(-\infty,2\)). Their intersection is ((0,2)).
Exam Tip
(A'=\(0,\infty\)) और (B'=\(-\infty,2\)) हैं। उनका प्रतिच्छेद ((0,2)) है।
