If \(A=\{1,3,5,7\}\) and \(B=\{3,7,9\}\), what is (\(A\cup B\)\setminus\(A\cap B\))?
Explanation opens after your attempt
Correct Answer
A. ( {1,5,9} )
Concept
The union is ( {1,3,5,7,9} ) and the intersection is ( {3,7} ). Removing the intersection leaves ( {1,5,9} ).
Why this answer is correct
The correct answer is A. ( {1,5,9} ). The union is ( {1,3,5,7,9} ) and the intersection is ( {3,7} ). Removing the intersection leaves ( {1,5,9} ).
Exam Tip
संघ ( {1,3,5,7,9} ) और प्रतिच्छेद ( {3,7} ) है। प्रतिच्छेद हटाने पर ( {1,5,9} ) बचता है।
