The probability of choosing a correct answer = 1/5
The probability of choosing a wrong answer = 4/5
Scores received on correct answer = +3
Scores received on wrong answer = -1
Scores on blank answer = 0
The average scores, in long run will be equal to the expected value. The expected value E, in this case will be:
Thus, in long run, the student will score -0.2 points on average.
