यदि \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{2,4,6,8\}\) और \(B=\{1,2,3,4\}\) है, तो (\(A^c\cup B\)^c) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{2,4,6,8\}\), and \(B=\{1,2,3,4\}\), what is (\(A^c\cup B\)^c)?
Explanation opens after your attempt
A. ({6,8})
Concept
\(A^c={1,3,5,7,9}\), and \(A^c\cup B={1,2,3,4,5,7,9}\). The remaining elements in (U) are (6,8).
Why this answer is correct
The correct answer is A. ({6,8}). \(A^c={1,3,5,7,9}\), and \(A^c\cup B={1,2,3,4,5,7,9}\). The remaining elements in (U) are (6,8).
Exam Tip
\(A^c={1,3,5,7,9}\) है और \(A^c\cup B={1,2,3,4,5,7,9}\) है। (U) में बचे (6,8) हैं।
