यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,2,5,7\}\) और \(B=\{2,4,5,8,10\}\) है, तो (\(A\cap B\)') क्या है?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,2,5,7\}\), and \(B=\{2,4,5,8,10\}\), what is (\(A\cap B\)')?
Explanation opens after your attempt
Correct Answer
B. ( {1,3,4,6,7,8,9,10} )
Concept
First \(A\cap B={2,5}\). The elements outside it in (U) are ({1,3,4,6,7,8,9,10}).
Why this answer is correct
The correct answer is B. ( {1,3,4,6,7,8,9,10} ). First \(A\cap B={2,5}\). The elements outside it in (U) are ({1,3,4,6,7,8,9,10}).
Exam Tip
पहले \(A\cap B={2,5}\) है। (U) में इसके बाहर के अवयव ({1,3,4,6,7,8,9,10}) हैं।
