25 weeks
178 + (3 x 25)
178 + 75 = 253
203 + (2 x 25)
203 + 50 = 253
Correct answer is 25 weeks.
Answer:
There isn't an answer for it because there is a variable
The probability that the person uses exactly one of the facilities = 95/130 .
<h3>What is Probability ?</h3>
Probability is the branch of Mathematics which helps to determine the likeliness of an event to happen.
The data is given and the probability that the person uses exactly one of the facilities is asked
73 people use the gym. P(G)
62 people use the swimming pool. P (S)
58 people use the track. P (T)
22 people use the gym and the pool. P (G ∩ P)
29 people use the pool and the track. P (P ∩ T)
25 people use the gym and the track. P (G ∩ T)
11 people use all three facilities. P (P∩G∩T)
P (PUGUT) = P(G) + P (S) + P (T) - P (G ∩ P) - P (P ∩ T) - P (G ∩ T) - 2 P (P∩G∩T)
73 + 62 + 58 -22-29-25 -11-11 = 95
The probability that the person uses exactly one of the facilities = 95/130 .
