Standard tests, such as the SAT or ACT or MCAT, tend to make extensive use of multiple-choice questions because they are easy to grade using software. If one such multiple choice question has possible correct answers of a, b, c, d, e, what is the probability of a wrong answer if the answer is a random guess

4/5

Step-by-step explanation:

Given that:

Number of options = a, b, c, d, e

Number of correct answer choice = 1

Therefore, number of wrong answers = 4

Recall :

Probability = (number required outcome / number of total possible outcomes)

P(wrong answer) :

Number of Required outcome = number of wrong answer choices = 4

Total answers = 5

Hence,

P(wrong answer) = 4 / 5 = 0.8
