A perfect square is a number that can be expressed as the product of two equal integers.
The only way to accurately calculate if a number is a perfect square is to find the factors. Before we go through the trouble of finding the factors, there is a quick trick you can use to help determine if you need even need to do the extra work.

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:
Substitute and
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:
