यदि \(U={x:x\in \mathbb{Z}, -3\le x\le 4}\) और \(A={x:x\in U, x^2<4}\) है, तो (A') में कितने तत्व हैं?
If \(U={x:x\in \mathbb{Z}, -3\le x\le 4}\) and \(A={x:x\in U, x^2<4}\), how many elements are in (A')?
Explanation opens after your attempt
C. (5)
Concept
Here \(U=\{-3,-2,-1,0,1,2,3,4\}\) and \(A=\{-1,0,1\}\). Hence (A') has (5) elements.
Why this answer is correct
The correct answer is C. (5). Here \(U=\{-3,-2,-1,0,1,2,3,4\}\) and \(A=\{-1,0,1\}\). Hence (A') has (5) elements.
Exam Tip
\(U=\{-3,-2,-1,0,1,2,3,4\}\) और \(A=\{-1,0,1\}\) है। इसलिए (A') में (5) तत्व हैं।
