Answer:
the first answer is correct
the second answer is correct if they messed up on the question and meant to ask for the MAD of set B
I think the 3rd answer is incorrect (I got 1.09), so you might want to double-check your 3rd answer since it is asking for "times bigger", not how much bigger, which means how many times larger is the MAD of set A than that of set B and to find how many times bigger a number is than another number, you have to divide the first number by the second number.

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:
<em>See attachment (2) for histogram</em>
Answer:
No
Step-by-step explanation:
This is not a function because there is no y and x intercept in the following graph as y=0
