यदि \(U=\{1,2,3,4,5,6,7\}\), \(A=\{1,2,5\}\) और \(B=\{2,4,6\}\) है, तो (\(A\cup B\)^c) क्या होगा?
If \(U=\{1,2,3,4,5,6,7\}\), \(A=\{1,2,5\}\), and \(B=\{2,4,6\}\), what is (\(A\cup B\)^c)?
Explanation opens after your attempt
A. ({3,7})
Concept
First \(A\cup B={1,2,4,5,6}\). Outside this in (U), (3) and (7) remain.
Why this answer is correct
The correct answer is A. ({3,7}). First \(A\cup B={1,2,4,5,6}\). Outside this in (U), (3) and (7) remain.
Exam Tip
पहले \(A\cup B={1,2,4,5,6}\) बनता है। (U) में इससे बाहर (3) और (7) बचे हैं।
