यदि \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3\}\), और \(B=\{3,4,5\}\), तो (n(P\(A'\cup B'\))) क्या है?
If \(U=\{1,2,3,4,5,6\}\), \(A=\{1,2,3\}\), and \(B=\{3,4,5\}\), then what is (n(P\(A'\cup B'\)))?
Explanation opens after your attempt
C. (32)
Concept
(A'\cup B'=\(A\cap B\)'={1,2,4,5,6}), so (n(P\(A'\cup B'\))=25=32). De Morgan's law makes counting easier.
Why this answer is correct
The correct answer is C. (32). (A'\cup B'=\(A\cap B\)'={1,2,4,5,6}), so (n(P\(A'\cup B'\))=25=32). De Morgan's law makes counting easier.
Exam Tip
(A'\cup B'=\(A\cap B\)'={1,2,4,5,6}), इसलिए (n(P\(A'\cup B'\))=25=32)। डी मॉर्गन नियम से गिनती आसान होती है।
