Looking for direction with solving this.

5. A multiple choice test has 4 potential answers for each question.

A. If a student is just guessing, what is the probability they guess the correct answer?

B. Suppose the test has 20 questions. What is the probability that they guess all 20 correct?

C. Suppose the test has 20 questions. What is the probability that they guess and do not get a single question correct?

D. What is the probability that a student guesses on all 20 questions and gets at least one correct?

We have not learned binomial yet, so this needs to be solved so I understand it with just simple statistics and probabilities.
