b)The probability of students who have joined in Yoga classes or Gym club is?
c) The probability of students who have not joined in Yoga classes is?

Answer 1

Answer:

Students go for yoga classes = 50% of 240 = 120

Students go for Gym club = 25% of 240 = 60

Students go for walking = 15% of 240 = 36.

Students go for laughing club = 240 - 120 - 60 - 36 = 24.

The probability of students who have not joined in any class or club is (240 - 120 - 60)/240 = 60/240 = 1/4

b)The probability of students who have joined in Yoga classes or Gym club is (120 + 60)/240 = 180/240 = 3/4

c) The probability of students who have not joined in Yoga classes is (240 - 120)/240 = 120/240 = 1/2
