There are 135 people in a sport centre. 73 people use the gym. 59 people use the swimming pool. 31 people use the track. 19 peop
le use the gym and the pool. 9 people use the pool and the track. 16 people use the gym and the track. 4 people use all three facilities. A person is selected at random. What is the probability that this person doesn't use any facility?
The probability indicating that this individual does not make use of any facility is 0.09. A breakdown of the number of users across various facilities leads to the calculation that assesses the likelihood someone uses at least one facility to be 0.91.
The probability that an individual does not utilize any facility is 0.0889. In a sports center housing 135 individuals, 73 use the gym, 59 use the swimming pool, and 31 use the track. The respective overlaps and total probabilities yield approximately this result.
This can be approached using trigonometry. The adjacent side corresponds to the length of the shadow, while the unknown represents the opposite side, which is Chad's height.
Tan (a) = opposite / adjacent
Opposite = tan(23) * 14.3 ft
Thus, the opposite side equals 6.1 ft, which is Chad's height
