यदि \(U=\mathbb{R}\), (A=(-5,2]) और (B=[-1,6)), तो (\(A\cap B\)') क्या है?
If \(U=\mathbb{R}\), (A=(-5,2]) and (B=[-1,6)), what is (\(A\cap B\)')?
Explanation opens after your attempt
Correct Answer
A. (\(-\infty,-1\)\cup\(2,\infty\))
Concept
\(A\cap B=[-1,2]\), so its complement is (\(-\infty,-1\)\cup\(2,\infty\)). Watch the endpoints in interval questions.
Why this answer is correct
The correct answer is A. (\(-\infty,-1\)\cup\(2,\infty\)). \(A\cap B=[-1,2]\), so its complement is (\(-\infty,-1\)\cup\(2,\infty\)). Watch the endpoints in interval questions.
Exam Tip
\(A\cap B=[-1,2]\), इसलिए उसका पूरक (\(-\infty,-1\)\cup\(2,\infty\)) है। अंतरालों में सीमा बिंदुओं पर ध्यान दें।
