यदि \(U=\{1,2,3,4,5,6\}\) और \(A=\{1,2,3,4\}\) है, तो (U-A) क्या होगा?
If \(U=\{1,2,3,4,5,6\}\) and \(A=\{1,2,3,4\}\), what is (U-A)?
Explanation opens after your attempt
A. ({5,6})
Concept
\(U-A=A^c\), so after removing the elements of (A), (5) and (6) remain. Link difference and complement with respect to (U).
Why this answer is correct
The correct answer is A. ({5,6}). \(U-A=A^c\), so after removing the elements of (A), (5) and (6) remain. Link difference and complement with respect to (U).
Exam Tip
\(U-A=A^c\) होता है, इसलिए (A) के तत्व हटाने पर (5) और (6) बचते हैं। अंतर और पूरक को (U) के संदर्भ में जोड़कर देखें।
