Multiple-choice questions have a special grading rule determined by your instructor. Assume that your instructor has decided to grade these questions in the following way:
If you submit an incorrect answer to a multiple-choice question with n options, you will lose 1/(n−1) of the credit for that question. Just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing.

If a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct, how much credit will you lose for that part of the question?

Answer:

The person will lose 0.25 credits.

Step-by-step explanation:

According to given condition, the deduction on wrong answer is:

Deduction = 1/(n-1)

where, n = no. of options in the question.

Therefore, if a person gives an incorrect answer to a multiple chice question which has 5 options. Then,

n = 5

and the deduction will be given as:

Deduction = 1/(5-1)

Deduction = 1/4

Deduction = 0.25 credit

The person will lose 0.25 credits.
