Question

Mastering presents homework items assigned by your instructor and works with you to answer them. Homework items typically have an introduction, possibly figures, and one or more parts for you to answer. What is the magic number? Multiple choice questions have a special grading rule determined by your instructor. Assume that your instructor has decided in grade theses questions in the following way. If you submit an incorrect answer to a multiple choice questions with if options, you will lose 1/(n - 1) of the credit for that questions. Just like the similar multiple-choice penalty necessary to prevent random guessing. If a multiple-choice question has five answer choices and your submit one wrong answer before getting the questions correct, how much credit will you have for that part of the question? 100% 50% 33% 25% 20%

Answer 1

for this answer it obtained 50% of its value

Step-by-step explanation:

The correction factor for multiple choice question is

.f = 1 / (n + 1)

Where n is the number of incorrect answers

Let's apply this expression to our case

An incorrect answer was given, so n = 1

.f = 1 / (1 + 1)

.f = 1/2 = 0.5

Therefore, for this answer it obtained 50% of its value
