यदि \(U=\mathbb{R}\) और (A=\(-\infty,2]\), तो (A') क्या है?
If \(U=\mathbb{R}\) and (A=\(-\infty,2]\), what is (A')?
Explanation opens after your attempt
Correct Answer
A. (\(2,\infty\))
Concept
(2) is included in (A), so it is not in the complement. In \(\mathbb{R}\), the complement is (\(2,\infty\)).
Why this answer is correct
The correct answer is A. (\(2,\infty\)). (2) is included in (A), so it is not in the complement. In \(\mathbb{R}\), the complement is (\(2,\infty\)).
Exam Tip
(2) (A) में शामिल है, इसलिए पूरक में (2) नहीं आएगा। \(\mathbb{R}\) में पूरक (\(2,\infty\)) है।
