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