यदि \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{1,2,3,4,5,6\}\) है, तो (\(A^c\)^c\cap{3,6,9}) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{1,2,3,4,5,6\}\), what is (\(A^c\)^c\cap{3,6,9})?
Explanation opens after your attempt
A. ({3,6})
Concept
(\(A^c\)^c=A). Therefore \(A\cap{3,6,9}={3,6}\).
Why this answer is correct
The correct answer is A. ({3,6}). (\(A^c\)^c=A). Therefore \(A\cap{3,6,9}={3,6}\).
Exam Tip
(\(A^c\)^c=A) होता है। इसलिए \(A\cap{3,6,9}={3,6}\) मिलेगा।
