यदि \(A\subseteq U\), तो (\(A'\cap A\)') किसके बराबर है?
If \(A\subseteq U\), what is (\(A'\cap A\)') equal to?
Explanation opens after your attempt
Correct Answer
A. (U)
Concept
\(A'\cap A=\varnothing\). Therefore (\(A'\cap A\)'=\varnothing'=U).
Why this answer is correct
The correct answer is A. (U). \(A'\cap A=\varnothing\). Therefore (\(A'\cap A\)'=\varnothing'=U).
Exam Tip
\(A'\cap A=\varnothing\) होता है। इसलिए (\(A'\cap A\)'=\varnothing'=U) है।
