यदि \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,3,5,7\}\) और \(B=\{2,3,5,8\}\), तो \(A'\cap B'\) क्या है?
If \(U=\{1,2,3,4,5,6,7,8\}\), \(A=\{1,3,5,7\}\), and \(B=\{2,3,5,8\}\), what is \(A'\cap B'\)?
Explanation opens after your attempt
Correct Answer
A. ({4,6})
Concept
(A'={2,4,6,8}) and (B'={1,4,6,7}), so the intersection is ({4,6}). Find both complements separately.
Why this answer is correct
The correct answer is A. ({4,6}). (A'={2,4,6,8}) and (B'={1,4,6,7}), so the intersection is ({4,6}). Find both complements separately.
Exam Tip
(A'={2,4,6,8}) और (B'={1,4,6,7}), अतः प्रतिच्छेद ({4,6}) है। ऐसे प्रश्न में दोनों पूरक अलग निकालें।
