Answer:
Step-by-step explanation:
Let's write out a case for two specific questions being correct and the rest being incorrect:
,
The 
represents the chances of getting the question correct, as there are 5 answers and 1 correct answer choice.
The 
represents the chances of getting the question incorrect, as there are 5 answers and 4 incorrect answer choices.
The equation above does show the student getting two answers correct and three answers incorrect, but it only shows one possible case of doing so.
We can choose any two of the five questions to be the ones the student gets correct. Therefore, we need to multiply this equation by the number ways we can choose 2 from 5 (order doesn't matter): 
.
Therefore, the probability the student gets two questions correct is:

Suppose that X is a vertical segment that lies on the y-axis with its beginning at origin and ending at the point (0,4). Then the length of this segment is 4 units.
If you vertically compress this segment by factor of 1/4 with the centre of compression at the origin, you recieve a segment that also lies on the y-axis with its beginning at origin and ending at the point (0,1) (the length of this image segment is 1 unit).
So, the question is: if a segment that lies on the y-axis with its beginning at origin and ending at the point (0,4) is vertically compressed <span>by factor of 1/4 with the centre of compression at the origin, what is the image of this transformation?

Answer:
Angle 1 = 128
Angle 2 = 52
Angle 3 = 47
Angle 4 = 133
Angle 5 = 81
Step-by-step explanation:
Angle 5 is 81
Angle 3 is 47
Angle 4 is 133
Angle 2 is 52
Angle 1 is 128
There is a lot of numbers like that.
For example:
-3 1/5; -3; -2 8/9; -2 1/2; -2 1/3; -2; -1 3/4; -1 3/5; -1; -9/10
And many, many more.
Do you have some numbers to choose from?
