यदि \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{2,4,6\}\) और \(B=\{4,6,8\}\) हैं, तो \(A'\cap B'\) क्या है?
If \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{2,4,6\}\), and \(B=\{4,6,8\}\), what is \(A'\cap B'\)?
Explanation opens after your attempt
Correct Answer
A. ({1,3,5,7})
Concept
(A'={1,3,5,7,8}) and (B'={1,2,3,5,7}). Their intersection is ({1,3,5,7}).
Why this answer is correct
The correct answer is A. ({1,3,5,7}). (A'={1,3,5,7,8}) and (B'={1,2,3,5,7}). Their intersection is ({1,3,5,7}).
Exam Tip
(A'={1,3,5,7,8}) और (B'={1,2,3,5,7}) हैं। इनका प्रतिच्छेद ({1,3,5,7}) है।
