Assume that random guesses are made for nine multiple choice questions on an SAT test, so that there are no 9 trials, each with probability of success (correct) given by p=0.4. Find the indicated probability for the number of correct answers. Find the probability that the number of correct answers is lower than 4.
P(X<4)=
