यदि \(A={x:x\in\mathbb{Z},-1\le x\le1}\) और \(B=\{0,1\}\) हैं, तो \(A\times B\) में कितने युग्म होंगे?
If \(A={x:x\in\mathbb{Z},-1\le x\le1}\) and \(B=\{0,1\}\), how many pairs are in \(A\times B\)?
Explanation opens after your attempt
A. (6)
Concept
\(A=\{-1,0,1\}\) has (3) elements and (B) has (2) elements. Therefore total pairs are \(3\times2=6\).
Why this answer is correct
The correct answer is A. (6). \(A=\{-1,0,1\}\) has (3) elements and (B) has (2) elements. Therefore total pairs are \(3\times2=6\).
Exam Tip
\(A=\{-1,0,1\}\) में (3) अवयव और (B) में (2) अवयव हैं। इसलिए कुल युग्म \(3\times2=6\) हैं।
