यदि \(U=\{1,2,3,4,5,6,7,8,9,10,11,12\}\) और \(A=\{3,6,9,12\}\) है, तो \(A^c\) क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9,10,11,12\}\) and \(A=\{3,6,9,12\}\), what is \(A^c\)?
Explanation opens after your attempt
A. ({1,2,4,5,7,8,10,11})
Concept
(A) contains multiples of (3), so the remaining elements of (U) form \(A^c\). For speed, cross out (A) from (U).
Why this answer is correct
The correct answer is A. ({1,2,4,5,7,8,10,11}). (A) contains multiples of (3), so the remaining elements of (U) form \(A^c\). For speed, cross out (A) from (U).
Exam Tip
(A) में (3) के गुणज हैं, इसलिए (U) में बचे हुए तत्व \(A^c\) हैं। जल्दी करने के लिए (U) से (A) को काटें।
