यदि \(A'\cup B'=U\), तो \(A\cap B\) के बारे में कौन सा निष्कर्ष सही है?
If \(A'\cup B'=U\), what conclusion is correct about \(A\cap B\)?
Explanation opens after your attempt
Correct Answer
A. \(A\cap B=\varnothing\)
Concept
(A'\cup B'=\(A\cap B\)'). If this is (U), then the complement of \(A\cap B\) is (U), so \(A\cap B=\varnothing\).
Why this answer is correct
The correct answer is A. \(A\cap B=\varnothing\). (A'\cup B'=\(A\cap B\)'). If this is (U), then the complement of \(A\cap B\) is (U), so \(A\cap B=\varnothing\).
Exam Tip
(A'\cup B'=\(A\cap B\)')। यदि यह (U) है, तो \(A\cap B\) का पूरक (U) है, इसलिए \(A\cap B=\varnothing\)।
