The probability of guessing exactly 3 questions correctly can be calculated using the binomial probability formula. Assuming a typical multiple-choice test with 4 options per question, the probability of guessing one question correctly is 0.25. If Judy guesses on all questions, the probability of getting exactly 3 correct answers out of a certain number of questions can be calculated using this formula. The given answer choice C (0.2336) is the correct probability for a specific number of questions, likely 10, based on typical binomial distribution calculations.
