यदि \(U=\mathbb{R}\), (A=(-3,4]) और (B=[1,6)), तो (\(A'\cap B'\)) क्या होगा?
If \(U=\mathbb{R}\), (A=(-3,4]) and (B=[1,6)), what is \(A'\cap B'\)?
Explanation opens after your attempt
Correct Answer
A. \(\(-\infty,-3]\cup[6,\infty\))
Concept
(A'\cap B'=\(A\cup B\)') and \(A\cup B=(-3,6)\). So the complement is (\(-\infty,-3]\cup[6,\infty\)).
Why this answer is correct
The correct answer is A. \(\(-\infty,-3]\cup[6,\infty\)). (A'\cap B'=\(A\cup B\)') and \(A\cup B=(-3,6)\). So the complement is (\(-\infty,-3]\cup[6,\infty\)).
Exam Tip
(A'\cap B'=\(A\cup B\)') और \(A\cup B=(-3,6)\)। इसलिए पूरक (\(-\infty,-3]\cup[6,\infty\)) है।
