We want to find the number of pairs of students who satisfy both the conditions given below:
- Both students in the pair have the same total marks.
- Both students do not belong to the same gender.
We now divide the students into two bins, one which contains boys and the other which contains girls, and perform pairwise comparisons within the bins. Will this approach give us the correct answer for the number of pairs?
Can anyone tell me how pairwise comparison is made in the above question? And what would be the correct approach for this?
