We can solve this question step by step.

✔ 1. We have to minus any number which was randomly chosen and that probability which is greater than 75 . So,
➡ 90 - 75 = 15

➡ Keiko's Chance of getting higher than 75 = 15/90
➡ Mitsugu's chance of getting higher than 75 = 15/90

➡ 15/90 × 15/90 = .0277777777 
= 2.78% chances
