A sample is taken at a school. the results show that 150 people work out at the gym, 200 play sports, and 100 people play sports
and workout at the gym. What is the probability that a student works out given that they also play sports
1 answer:
Probability = number of desired outcome / Total number of possible outcomes
According to the given data,
number of people work out at gym = 150
number of people play sports = 200
number of people who do both = 100
The total number of sudents = 150 + 200 + 100 = 450
Probability of a student who do both = 100 / 450 = 2 / 9
