यदि \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3\}\) और \(B=\{3,4,5\}\) हैं, तो \(A^{c}\cup B^{c}\) क्या है?
If \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3\}\), and \(B=\{3,4,5\}\), what is \(A^{c}\cup B^{c}\)?
Explanation opens after your attempt
Correct Answer
A. ({1,2,4,5,6})
Concept
\(A^{c}={4,5,6}\) and \(B^{c}={1,2,6}\), so their union is ({1,2,4,5,6}). This also matches (\(A\cap B\)^{c}).
Why this answer is correct
The correct answer is A. ({1,2,4,5,6}). \(A^{c}={4,5,6}\) and \(B^{c}={1,2,6}\), so their union is ({1,2,4,5,6}). This also matches (\(A\cap B\)^{c}).
Exam Tip
\(A^{c}={4,5,6}\) और \(B^{c}={1,2,6}\), उनका संघ ({1,2,4,5,6}) है। यह (\(A\cap B\)^{c}) से भी मिलता है।
