यदि \(A=\{1,2,3\}\) और \(B=\{2,3,4\}\) हैं, तो \(A\times B\) में कितने युग्म ((x,y)) ऐसे हैं कि (x+y>5)?
If \(A=\{1,2,3\}\) and \(B=\{2,3,4\}\), how many pairs ((x,y)) in \(A\times B\) satisfy (x+y>5)?
Explanation opens after your attempt
A. (3)
Concept
The valid pairs are ((2,4),(3,3),(3,4)). Pairs with (x+y=5) are not included.
Why this answer is correct
The correct answer is A. (3). The valid pairs are ((2,4),(3,3),(3,4)). Pairs with (x+y=5) are not included.
Exam Tip
सही युग्म ((2,4),(3,3),(3,4)) हैं। (x+y=5) वाले युग्म शामिल नहीं होंगे।
