यदि \(U={1,2,\ldots,12}\), \(A=\{2,4,6,8,10,12\}\) और \(B=\{3,6,9,12\}\) हैं, तो (\(A\cup B\)') क्या है?
If \(U={1,2,\ldots,12}\), \(A=\{2,4,6,8,10,12\}\), and \(B=\{3,6,9,12\}\), what is (\(A\cup B\)')?
Explanation opens after your attempt
A. ({1,5,7,11})
Simple Explanation
\(A\cup B={2,3,4,6,8,9,10,12}\) है। (U) में इसके बाहर के तत्व (1,5,7,11) हैं। / \(A\cup B={2,3,4,6,8,9,10,12}\). The elements outside it in (U) are (1,5,7,11).
