यदि \(A=\{2,3,5,7,11\}\) और \(B=\{1,3,5,9,11\}\) हैं, तो (\(A\setminus B\)\cup\(B\setminus A\)) क्या है?
If \(A=\{2,3,5,7,11\}\) and \(B=\{1,3,5,9,11\}\), what is (\(A\setminus B\)\cup\(B\setminus A\))?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,7,9} )
Concept
\(A\setminus B={2,7}\) and \(B\setminus A={1,9}\). Their union is ({1,2,7,9}).
Why this answer is correct
The correct answer is A. ( {1,2,7,9} ). \(A\setminus B={2,7}\) and \(B\setminus A={1,9}\). Their union is ({1,2,7,9}).
Exam Tip
\(A\setminus B={2,7}\) और \(B\setminus A={1,9}\) है। दोनों का संघ ({1,2,7,9}) है।
