Answer:
The probability that the student will not guess correctly on any one question is 4/5
Explanation:
The question posed is an application of the binomial probability distribution.
We have been informed that the test has multiple choice questions with 5 choices for each answer that only one answer is correct for each question.
If the student guesses the answer to each question, then the probability that the student will guess correctly on any one question is 1/5.
Therefore, the probability that the student will not guess correctly on any one question is;
1 - 1/5 = 4/5
