यदि \(U=\{1,2,3,4,5,6\}\) और \(A=\{1,5,6\}\) है, तो (A-A') क्या होगा?
If \(U=\{1,2,3,4,5,6\}\) and \(A=\{1,5,6\}\), what will (A-A') be?
Explanation opens after your attempt
Correct Answer
A. ({1,5,6})
Concept
(A') has no element of (A), so (A-A'=A). Use the disjointness of a set and its complement.
Why this answer is correct
The correct answer is A. ({1,5,6}). (A') has no element of (A), so (A-A'=A). Use the disjointness of a set and its complement.
Exam Tip
(A') में (A) का कोई अवयव नहीं होता, इसलिए (A-A'=A) है। पूरक असंयुक्तता का उपयोग करें।
