यदि \(A=\{p,q\}\) और \(B=\{r,s\}\) हैं, तो \(B\times A\) कौन सा है?
If \(A=\{p,q\}\) and \(B=\{r,s\}\), which is \(B\times A\)?
Explanation opens after your attempt
Correct Answer
B. ({(r,p),(r,q),(s,p),(s,q)})
Concept
In \(B\times A\), the first component is from (B) and the second from (A). Do not confuse \(A\times B\) with \(B\times A\).
Why this answer is correct
The correct answer is B. ({(r,p),(r,q),(s,p),(s,q)}). In \(B\times A\), the first component is from (B) and the second from (A). Do not confuse \(A\times B\) with \(B\times A\).
Exam Tip
\(B\times A\) में पहला अवयव (B) से और दूसरा (A) से लिया जाता है। \(A\times B\) और \(B\times A\) को अलग समझें।
