यदि \(U=\{1,2,3,4,5\}\) और \(A=\{1,2\}\), तो \(A^{c}\setminus A\) क्या है?
If \(U=\{1,2,3,4,5\}\) and \(A=\{1,2\}\), what is \(A^{c}\setminus A\)?
Explanation opens after your attempt
Correct Answer
A. ({3,4,5})
Concept
\(A^{c}={3,4,5}\) and it has no element of (A), so the difference remains the same. Subtracting a disjoint set does not change it.
Why this answer is correct
The correct answer is A. ({3,4,5}). \(A^{c}={3,4,5}\) and it has no element of (A), so the difference remains the same. Subtracting a disjoint set does not change it.
Exam Tip
\(A^{c}={3,4,5}\) और इसमें (A) का कोई अवयव नहीं है, इसलिए अंतर वही रहेगा। असंपाती समुच्चयों में घटाने से समुच्चय नहीं बदलता।
