यदि \(U=\{1,2,3,4,5,6,7,8\}\) और \(A=\{3,4,5,6\}\) है, तो \(A'\cap A\) कौन सा है?
If \(U=\{1,2,3,4,5,6,7,8\}\) and \(A=\{3,4,5,6\}\), which is \(A'\cap A\)?
Explanation opens after your attempt
Correct Answer
A. \(\varnothing\)
Concept
(A) and (A') are disjoint, so their intersection is \(\varnothing\). No element of (A) remains in its complement.
Why this answer is correct
The correct answer is A. \(\varnothing\). (A) and (A') are disjoint, so their intersection is \(\varnothing\). No element of (A) remains in its complement.
Exam Tip
(A) और (A') असंयुक्त होते हैं, इसलिए उनका प्रतिच्छेद \(\varnothing\) है। पूरक में (A) का कोई अवयव नहीं रहता।
