If \(A=\{2,4,6\}\) and \(B=\{1,3\}\), which pair is an element of \(A\times B\)?
Explanation opens after your attempt
Correct Answer
B. ((4,3))
Concept
In ((4,3)), \(4\in A\) and \(3\in B\), so it is correct. Having the elements present is not enough; their positions must be correct.
Why this answer is correct
The correct answer is B. ((4,3)). In ((4,3)), \(4\in A\) and \(3\in B\), so it is correct. Having the elements present is not enough; their positions must be correct.
Exam Tip
((4,3)) में \(4\in A\) और \(3\in B\), इसलिए यह सही है। केवल तत्व मौजूद होना काफी नहीं, सही स्थान भी जरूरी है।
