A multiple-choice quiz has 5 questions with 4 answer choices each. A student guesses randomly on every question. To estimate the probability of getting at least 3 correct, a student runs a simulation: for each question generate a random integer 1–4, count "correct" when the number is 1, record whether at least 3 of the 5 are correct, and repeat 2000 trials. The simulation produced 231 successes. Which interpretation of the simulation results is correct?
