Step-by-step explanation:
No. of students not playing any sport = 60°x1800/360° = 300
Rest of students playing other sports = 1800-300 = 1500
Ratio of students playing football, cricket and hockey is 5:3:2
Let the no. of students playing each sport = x
Football playing students = 5x
Cricket playing students = 3x
Hockey playing students = 2x
5x+3x+2x = 1500
10x = 1500
x = 150
Football playing students = 750
Cricket playing students = 450
Hockey playing students = 300
Probability of non-sport playing student to be college sports council = Possible outcome/Total no. of outcome
Probability = 300/1800 = 1/6
