\(यदि (U=\mathbb{R}) और (A={x:x<2\) या \(x\ge 8}), तो (A') क्या है\)?
\(If (U=\mathbb{R}) and (A={x:x<2\) or \(x\ge 8}), what is (A')\)?
Explanation opens after your attempt
Correct Answer
A. \([2,8))
Concept
Outside (A) are the real numbers satisfying \(2\le x<8\). Therefore (A'=[2,8)).
Why this answer is correct
The correct answer is A. \([2,8)). Outside (A) are the real numbers satisfying \(2\le x<8\). Therefore (A'=[2,8)).
Exam Tip
(A) के बाहर वे वास्तविक संख्याएँ हैं जिनके लिए \(2\le x<8\)। इसलिए (A'=[2,8)) है।
