यदि \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{1,3,5,7,9\}\) और \(B=\{2,3,5,8\}\) है, तो (\(A\cap B\)') क्या है?
If \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{1,3,5,7,9\}\), and \(B=\{2,3,5,8\}\), what is (\(A\cap B\)')?
Explanation opens after your attempt
Correct Answer
A. ({1,2,4,6,7,8,9})
Concept
\(A\cap B={3,5}\), so removing these from (U) gives the complement. Finding the intersection first is necessary.
Why this answer is correct
The correct answer is A. ({1,2,4,6,7,8,9}). \(A\cap B={3,5}\), so removing these from (U) gives the complement. Finding the intersection first is necessary.
Exam Tip
\(A\cap B={3,5}\), इसलिए (U) से इन्हें हटाने पर पूरक मिलता है। पहले प्रतिच्छेद निकालना जरूरी है।
