यदि \(U={x:x\in \mathbb{Z}, -5\le x\le 5}\) और \(A={x:x\in U, |x|\le 2}\), तो (A') में कितने तत्व हैं?
If \(U={x:x\in \mathbb{Z}, -5\le x\le 5}\) and \(A={x:x\in U, |x|\le 2}\), how many elements are in (A')?
Explanation opens after your attempt
C. (6)
Concept
(U) has (11) elements and \(A=\{-2,-1,0,1,2\}\) has (5) elements. So (A') has (6) elements.
Why this answer is correct
The correct answer is C. (6). (U) has (11) elements and \(A=\{-2,-1,0,1,2\}\) has (5) elements. So (A') has (6) elements.
Exam Tip
(U) में (11) तत्व हैं और \(A=\{-2,-1,0,1,2\}\) में (5) तत्व हैं। इसलिए (A') में (6) तत्व हैं।
