On a quiz there are four multiple-choice questions worth 3 points each and two true/false questions
worth 1 point each. Each multiple-choice question has five possible choices. If a student randomly
guesses on each question, what is the expected value of the student's score on the test?
2.8
5.4
3.4
1.8
Can anyone help me ples?

3.4

Step-by-step explanation:

Since we have given that

Number of multiple choice question = 4

Number of true false questions = 2

Number of points for each multiple choice question = 3

Number of points for each true false question = 1

Number of choices in multiple choice = 5

Probability of getting correct answer in multiple choice question =   1/5

Probability of getting correct answer in true false question = 1/2  

answer would be 17/5 which is equal to 3.4

stops on an even number.
