यदि \(A=\{1,3,5\}\) और \(B=\{2,4,6\}\) हैं, तो \(A\times B\) में कितने युग्म ((x,y)) ऐसे हैं कि (x+y>7)?
If \(A=\{1,3,5\}\) and \(B=\{2,4,6\}\), how many pairs ((x,y)) in \(A\times B\) satisfy (x+y>7)?
Explanation opens after your attempt
Correct Answer
A. (3)
Concept
The valid pairs are ((3,6),(5,4),(5,6)). In boundary inequalities, check whether equality is included or not.
Why this answer is correct
The correct answer is A. (3). The valid pairs are ((3,6),(5,4),(5,6)). In boundary inequalities, check whether equality is included or not.
Exam Tip
सही युग्म ((3,6),(5,4),(5,6)) हैं। सीमा वाली असमानता में बराबरी शामिल है या नहीं यह जरूर देखें।
