यदि \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,7\}\) और \(B=\{2,3,8\}\) है, तो (\(A\cup B\)^c) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,7\}\), and \(B=\{2,3,8\}\), what will (\(A\cup B\)^c) be?
Explanation opens after your attempt
Correct Answer
A. ({4,5,6})
Concept
First \(A\cup B={1,2,3,7,8}\). Outside this in (U), (4,5,6) remain.
Why this answer is correct
The correct answer is A. ({4,5,6}). First \(A\cup B={1,2,3,7,8}\). Outside this in (U), (4,5,6) remain.
Exam Tip
पहले \(A\cup B={1,2,3,7,8}\) है। (U) में इससे बाहर (4,5,6) बचे हैं।
