Mohit Soni · Accepted Answer

50% of 240 = 120 ; so 120 students go for yoga
25% of 240 = 60 ; so 60 students go for gym
15% of 240 = 36 ; so 36 students go for morning walk
no of students joined laughing club = 240 - (120+60+36)
=240-216
=24 ; so 24 students go for laughing club
now coming on the questions you need to answer:
A) students joined laughing club = 24
total students = 240
P(student for laughing club) = students joined laughing club /
total students
=24/240
1/10 or 0 1
B)students joined any class or club =
120 (students go for yoga) + 60 (students go for gym )+ 24
(students go for laughing club) [note that morning walk is
not consider as any class or club so it will not be
added]
= 204
total students = 240
P(student who have joined club or class) = students joined any
class or club / total students
= 204/240
=0 85
