यदि \(U={1,2,\ldots,15}\), \(A=\{1,5,9,13\}\), \(B=\{2,5,8,11,14\}\), तो (\(A\cap B\)') क्या है?
If \(U={1,2,\ldots,15}\), \(A=\{1,5,9,13\}\), and \(B=\{2,5,8,11,14\}\), what is (\(A\cap B\)')?
Explanation opens after your attempt
A. ({1,2,3,4,6,7,8,9,10,11,12,13,14,15})
Concept
\(A\cap B={5}\). Therefore (\(A\cap B\)') contains all elements of (U) except (5).
Why this answer is correct
The correct answer is A. ({1,2,3,4,6,7,8,9,10,11,12,13,14,15}). \(A\cap B={5}\). Therefore (\(A\cap B\)') contains all elements of (U) except (5).
Exam Tip
\(A\cap B={5}\) है। इसलिए (\(A\cap B\)') में (5) को छोड़कर (U) के सभी सदस्य होंगे।
