यदि \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{1,2,3,4\}\) और \(B=\{4,5,6\}\) है, तो \(A^c-B^c\) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9\}\), \(A=\{1,2,3,4\}\), and \(B=\{4,5,6\}\), what is \(A^c-B^c\)?
Explanation opens after your attempt
Correct Answer
A. ({5,6})
Concept
\(A^c-B^c=A^c\cap B\). Here \(A^c={5,6,7,8,9}\) and \(B=\{4,5,6\}\), so the answer is ({5,6}).
Why this answer is correct
The correct answer is A. ({5,6}). \(A^c-B^c=A^c\cap B\). Here \(A^c={5,6,7,8,9}\) and \(B=\{4,5,6\}\), so the answer is ({5,6}).
Exam Tip
\(A^c-B^c=A^c\cap B\) होता है। \(A^c={5,6,7,8,9}\) और \(B=\{4,5,6\}\), इसलिए उत्तर ({5,6}) है।
