Assume that random guesses are made for twelve multiple choice questions on a medical admissions test, so that there are n = 12 trials, each with a probability of success (correct) given by p = 0.20. Find the probability that the number x of correct answers is fewer than 4. (I) The probability that the number x of correct answers is fewer than 4 is D. (Round to three decimal places as needed.)
