Answer:
4/5 or -4/5
Step-by-step explanation:
We are going to use the Pythagorean Identity:
We are given the value of which is 3/5 so plug that in:
Simplify:
Subtract 9/25 on both sides:
Take the square root of both sides:
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 .

Answer:
Step-by-step explanation:
4a - (4a-3)
= 4a -1(4a - 3)
= 4a - 4a + 3 <--- Distributing the -1 over the parenthes
= 3 <---- ( as 4a - 4a = 0)
