Um, how does this help?
IS IT B?
To find the probability of answering all 5 questions correctly, we need to determine the probability of getting each question right and then multiply those probabilities together.
Since each question has 5 possible answers, the probability of guessing the correct answer to each question is 1/5. Therefore, the probability of answering all 5 questions correctly is (1/5) * (1/5) * (1/5) * (1/5) * (1/5) = 1/3125.
So the correct answer is A. 1/3,125.
