यदि \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,3,5,7\}\) और \(B=\{2,3,5,8\}\) हैं, तो (\(A\cup B\)^{c}) क्या है?
If \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,3,5,7\}\), and \(B=\{2,3,5,8\}\), what is (\(A\cup B\)^{c})?
Explanation opens after your attempt
Correct Answer
A. ({4,6})
Concept
\(A\cup B={1,2,3,5,7,8}\), so the complement is ({4,6}). Finding the union first is safer.
Why this answer is correct
The correct answer is A. ({4,6}). \(A\cup B={1,2,3,5,7,8}\), so the complement is ({4,6}). Finding the union first is safer.
Exam Tip
\(A\cup B={1,2,3,5,7,8}\), इसलिए पूरक ({4,6}) है। पहले संघ निकालना अधिक सुरक्षित है।
