यदि \(U={1,2,\ldots,12}\), \(A=\{1,3,5,7,9,11\}\) और \(B=\{2,3,5,7,11\}\), तो (\(A'\cup B'\)') क्या है?
If \(U={1,2,\ldots,12}\), \(A=\{1,3,5,7,9,11\}\) and \(B=\{2,3,5,7,11\}\), what is (\(A'\cup B'\)')?
Explanation opens after your attempt
Correct Answer
A. \({3,5,7,11})
Concept
By De Morgan, (\(A'\cup B'\)'=A\cap B), which is ({3,5,7,11}). Simplify the outer complement using the law.
Why this answer is correct
The correct answer is A. \({3,5,7,11}). By De Morgan, (\(A'\cup B'\)'=A\cap B), which is ({3,5,7,11}). Simplify the outer complement using the law.
Exam Tip
डी मॉर्गन से (\(A'\cup B'\)'=A\cap B), जो ({3,5,7,11}) है। बाहरी पूरक को नियम से सरल करें।
