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 .

The length of the swimming pool is, 230 centimeters in length, and 216 centimeters in width. How I got my answer.
I first divided 446÷2=223, then I subtracted 223-7=216, that's width. Now I realise that there is 7 remaining, so I added 223+7=230, that's length!!
So to double check my work I added the width and length together, 216+230=446.
I hope this helps!
Answer:
pencils amount = 9 pens amount= 9
Step-by-step explanation:
We start this problem forming two linear equations system.
3*X+7*Y=90
Where X is the amount of pencils and Y is the amount of pens
The second equation is given by the statement, the amount of pencils is equal to the amount of pens, so the second equation is:
X=Y
Merging both equations we have:
3*X+7*X=90
Solving for X we have:
10*X=90
X=9
X=Y=9
