यदि \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,3,4\}\) और \(B=\{3,4,5,6\}\), तो (\(A^{c}\cup B\)^{c}) क्या है?
If \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,2,3,4\}\), and \(B=\{3,4,5,6\}\), what is (\(A^{c}\cup B\)^{c})?
Explanation opens after your attempt
Correct Answer
A. ({1,2})
Concept
\(A^{c}={5,6,7,8}\) and \(A^{c}\cup B={3,4,5,6,7,8}\), so the complement is ({1,2}). Do not skip steps.
Why this answer is correct
The correct answer is A. ({1,2}). \(A^{c}={5,6,7,8}\) and \(A^{c}\cup B={3,4,5,6,7,8}\), so the complement is ({1,2}). Do not skip steps.
Exam Tip
\(A^{c}={5,6,7,8}\) और \(A^{c}\cup B={3,4,5,6,7,8}\), इसलिए पूरक ({1,2}) है। चरण न छोड़ें।
