Answer:





Step-by-step explanation:
Given


The sample space is as follows:
This implies that we construct possible outcome that Ebony selects a bill, returns the bill and then select another.
This means that there are possibilities that the same bill is selected twice.
So, the sample space is as follows:


Solving (a): 
This means that the first and second bill selected are the same.
The outcome of this are:


The probability is:



Solving (a): 
This means that the second bill selected is less than the first.
The outcome of this are:


The probability is:



Solving (c): 
This means that the first and the second bill are even
The outcome of this are:


The probability is:


Solving (e): 
This question has missing details.
The correct question is to determine the probability that, the sum of both bills is less than 10
The outcome of this are:


The probability is:


Solving (d): 
This question has missing details.
The correct question is to determine the probability that, exactly one of the bills is 0dd
The outcome of this are:


The probability is:

So the question is asking to define and compare radian measure to degree measure, and base on my further research and further understanding about the said topic, the answer would be the following:
#1 in calculating arc length, the angle MUST be in radians.
#2 in formulas such as that for area of a circle (A = pi*r^2), pi (a measure of central angle) is already in radians.
#3 <span> in Calculus (which you may or may not study later on), angles are commonly expressed in radians and not in degrees.</span>
