यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,3,5,7\}\) और \(B=\{2,3,6,7\}\) हैं, तो (\(A\cup B\)') क्या है?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,3,5,7\}\), and \(B=\{2,3,6,7\}\), what is (\(A\cup B\)')?
Explanation opens after your attempt
Correct Answer
A. ({4,8,9,10})
Concept
\(A\cup B={1,2,3,5,6,7}\). Removing it from (U) gives ({4,8,9,10}).
Why this answer is correct
The correct answer is A. ({4,8,9,10}). \(A\cup B={1,2,3,5,6,7}\). Removing it from (U) gives ({4,8,9,10}).
Exam Tip
\(A\cup B={1,2,3,5,6,7}\) है। (U) से इसे हटाने पर ({4,8,9,10}) मिलता है।
