Answer:
The playground covers
of a square mile
Step-by-step explanation:
The playground is a rectangular ground. The area of a rectangle is given by legth * width, hence,
The area of the playground is length * width
Area =
sq. mi
Hence the playground cover
of a square mile
Answer:
(a) Sample Space

(b) PMF

(c) CDF

Step-by-step explanation:
Solving (a): The sample space
From the question, we understand that at most 3 cars will be repaired.
This implies that, the number of cars will be 0, 1, 2 or 3
So, the sample space is:

Solving (b): The PMF
From the question, we have:



can be represented as:
![P(1) + P(2) = 0.5[P(0) + P(3)]](https://tex.z-dn.net/?f=P%281%29%20%2B%20P%282%29%20%3D%200.5%5BP%280%29%20%2B%20P%283%29%5D)
Substitute
and 
![P(1) + P(1) = 0.5[P(0) + P(0)]](https://tex.z-dn.net/?f=P%281%29%20%2B%20P%281%29%20%3D%200.5%5BP%280%29%20%2B%20P%280%29%5D)
![2P(1) = 0.5[2P(0)]](https://tex.z-dn.net/?f=2P%281%29%20%3D%200.5%5B2P%280%29%5D)


Also note that:

Substitute
and 


Substitute 



Solve for P(1)

To calculate others, we have:






Hence, the PMF is:

<em>See attachment (1) for histogram</em>
Solving (c): The CDF ; F(x)
This is calculated as:

For x = 0;
We have:


For x = 1



For x = 2



For x = 3



Hence, the CDF is:

I think it's because of the issue of sustainability and pollution. Many companies have been expanding their business in Florida. Florida used to be one of the best producers in the US. However, because of the on-going expansion, people moving in and out of the state can lead to overpopulation and shortage on food supply. Florida is also known for its marine ecology. Expansion can also <span>severe pollution and extinction of some animals that are found in the state</span>
