Standardized Test: You are trying to answer a multiple choice question on a standardized test. There are four choices. If you get the question right, you gain 1
one point, and if you get it wrong, you lose point. Assume you have no idea what the right answer is, so you pick one of the choices at random. What is
the expected value of the number of points you get?
What is the expected value of the number of points you get? Round the answer to two decimal places.
The expected value of the number of points you get is
x
5

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
