यदि \(A={x:x\in\mathbb{Z},-2\le x\le1}\) और \(B=\{0,2\}\) हैं, तो \(A\times B\) में कितने युग्म होंगे?
If \(A={x:x\in\mathbb{Z},-2\le x\le1}\) and \(B=\{0,2\}\), how many pairs are in \(A\times B\)?
Explanation opens after your attempt
A. (8)
Concept
\(A=\{-2,-1,0,1\}\) has (4) elements and (B) has (2) elements. Therefore total pairs are \(4\times2=8\).
Why this answer is correct
The correct answer is A. (8). \(A=\{-2,-1,0,1\}\) has (4) elements and (B) has (2) elements. Therefore total pairs are \(4\times2=8\).
Exam Tip
\(A=\{-2,-1,0,1\}\) में (4) अवयव हैं और (B) में (2) अवयव हैं। इसलिए कुल युग्म \(4\times2=8\) होंगे।
