यदि \(U={1,2,\ldots,12}\), \(A=\{2,3,5,7,11\}\) और \(B=\{1,3,5,9,11\}\), तो (\(A\cup B\)') क्या है?
If \(U={1,2,\ldots,12}\), \(A=\{2,3,5,7,11\}\) and \(B=\{1,3,5,9,11\}\), what is (\(A\cup B\)')?
Correct answer and explanation
A. ({4,6,8,10,12})
Simple Explanation
\(A\cup B={1,2,3,5,7,9,11}\), इसलिए (U) में बचे तत्व ({4,6,8,10,12}) हैं। पूरक निकालते समय (U) जरूरी है। / \(A\cup B={1,2,3,5,7,9,11}\), so remaining elements in (U) are ({4,6,8,10,12}). The universal set is essential for complements.
