What is the probability of getting one question right?

If there were just one question, then the probability of guessing correctly would be 1/3. Since all the answers are independent (the answer to one question has no bearing on the answers to the others), then this is the case with each question, so the chances of guessing all answers correctly is 1/3 × 1/3 × 1/3 = 1/27.
