यदि \(U=\{a,b,c,d,e,f,g,h\}\), \(A=\{a,d,g\}\) और \(B=\{b,d,e,h\}\), तो \(A'\cap B'\) क्या है?
If \(U=\{a,b,c,d,e,f,g,h\}\), \(A=\{a,d,g\}\), and \(B=\{b,d,e,h\}\), what is \(A'\cap B'\)?
Explanation opens after your attempt
Correct Answer
A. ({c,f})
Concept
\(A'\cap B'\) contains elements not in \(A\cup B\). Since \(A\cup B={a,b,d,e,g,h}\), the answer is ({c,f}).
Why this answer is correct
The correct answer is A. ({c,f}). \(A'\cap B'\) contains elements not in \(A\cup B\). Since \(A\cup B={a,b,d,e,g,h}\), the answer is ({c,f}).
Exam Tip
\(A'\cap B'\) वही सदस्य हैं जो \(A\cup B\) में नहीं हैं। \(A\cup B={a,b,d,e,g,h}\), इसलिए उत्तर ({c,f}) है।
