यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,2,3,4,5\}\) और \(B=\{4,5,6,7,8\}\) है, तो \(A^c-B^c\) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,2,3,4,5\}\), and \(B=\{4,5,6,7,8\}\), what is \(A^c-B^c\)?
Explanation opens after your attempt
Correct Answer
A. ({6,7,8})
Concept
\(A^c-B^c=A^c\cap B\). Since \(A^c={6,7,8,9,10}\), the common part with (B) is ({6,7,8}).
Why this answer is correct
The correct answer is A. ({6,7,8}). \(A^c-B^c=A^c\cap B\). Since \(A^c={6,7,8,9,10}\), the common part with (B) is ({6,7,8}).
Exam Tip
\(A^c-B^c=A^c\cap B\) होता है। \(A^c={6,7,8,9,10}\), इसलिए (B) के साथ साझा भाग ({6,7,8}) है।
