यदि \(U=\{1,2,3,4,5,6,7\}\), \(A=\{1,3,5\}\) और \(B=\{2,3,6\}\) है, तो \(A'\cup B'\) क्या है?
If \(U=\{1,2,3,4,5,6,7\}\), \(A=\{1,3,5\}\), and \(B=\{2,3,6\}\), what is \(A'\cup B'\)?
Explanation opens after your attempt
Correct Answer
A. ({1,2,4,5,6,7})
Concept
(A'={2,4,6,7}) and (B'={1,4,5,7}), so the union is ({1,2,4,5,6,7}). It is also equal to (\(A\cap B\)').
Why this answer is correct
The correct answer is A. ({1,2,4,5,6,7}). (A'={2,4,6,7}) and (B'={1,4,5,7}), so the union is ({1,2,4,5,6,7}). It is also equal to (\(A\cap B\)').
Exam Tip
(A'={2,4,6,7}) और (B'={1,4,5,7}), इसलिए संघ ({1,2,4,5,6,7}) है। यह (\(A\cap B\)') के बराबर भी है।
