यदि \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3,4\}\) और \(B=\{3,4,5\}\) है, तो \(A'\cap B'\) क्या है?
If \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3,4\}\), and \(B=\{3,4,5\}\), what is \(A'\cap B'\)?

Correct Answer
A. ({6})
Concept
(A'={5,6}) and (B'={1,2,6}), so the intersection is ({6}). Find complements separately and then combine.
Why this answer is correct
The correct answer is A. ({6}). (A'={5,6}) and (B'={1,2,6}), so the intersection is ({6}). Find complements separately and then combine.
Exam Tip
(A'={5,6}) और (B'={1,2,6}), इसलिए प्रतिच्छेद ({6}) है। पूरक अलग-अलग निकालकर मिलाएं।
