यदि \(A=\{0,1\}\), \(B=\{x,y,z\}\) हैं, तो \(A\times B\) में ((1,y)) का स्थान किस कारण सही है?
If \(A=\{0,1\}\), \(B=\{x,y,z\}\), why is ((1,y)) correctly placed in \(A\times B\)?
Explanation opens after your attempt
Correct Answer
A. क्योंकि \(1\in A\) और \(y\in B\)because \(1\in A\) and \(y\in B\)
Concept
\((1,y)\in A\times B\) only when \(1\in A\) and \(y\in B\). Do not reverse order while checking membership.
Why this answer is correct
The correct answer is A. क्योंकि \(1\in A\) और \(y\in B\) / because \(1\in A\) and \(y\in B\). \((1,y)\in A\times B\) only when \(1\in A\) and \(y\in B\). Do not reverse order while checking membership.
Exam Tip
\((1,y)\in A\times B\) तभी होगा जब \(1\in A\) और \(y\in B\) हो। सदस्यता जांच में क्रम न बदलें।
