ratelena [41]

Answer:

a) 0.5

Step-by-step explanation:

a)

Let T be the event that person uses trails daily and E be the event that person uses trails for exercise.

We have to find the probability that person uses the trails for exercise given that the person uses trails daily which can be denoted as P(E/T).

P(E/T)= P(E∩T)/P(T)

We are given that P(T)=0.24 and P(E∩T)=0.12. So,

P(E/T)= 0.12/0.24

P(E/T)= 0.5

Thus, the probability that person uses the trails for exercise given that the person uses trails daily is 50%
