assuming the student is totally ignorant of the subject matter, and guesses randomly, the the chance of a correct answer is 1/5.

That makes it easy to tell what the chance is of a wrong answer.

I'm not sure of the second question. I understand the 1/5 chance of answering correctly but I'm not sure of the probability of answering incorrectly. Would it be 1 - 1/5?
