यदि \(U=\{1,2,3,4,5\}\) और \(A=\{1,2\}\), तो \(A\setminus A^{c}\) क्या है?
If \(U=\{1,2,3,4,5\}\) and \(A=\{1,2\}\), what is \(A\setminus A^{c}\)?
Explanation opens after your attempt
Correct Answer
A. ({1,2})
Concept
(A) and \(A^{c}\) have no common element, so \(A\setminus A^{c}=A\). Use the disjoint property with complements.
Why this answer is correct
The correct answer is A. ({1,2}). (A) and \(A^{c}\) have no common element, so \(A\setminus A^{c}=A\). Use the disjoint property with complements.
Exam Tip
(A) और \(A^{c}\) में कोई साझा अवयव नहीं है, इसलिए \(A\setminus A^{c}=A\)। पूरक के साथ अंतर में असंपाती गुण उपयोग करें।
