Question
Assume that random guesses are made for nine multiple choice questions on an SAT test, so that there are n=9 trials, each with probability of success (correct) given by p=0.65. Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than 4. P(X <4) =D (Round to four decimal places as needed.)
