HELP PLEASE!!!
Assume that random guesses are made for 7 multiple-choice questions on an SAT test so that there are n=7 trials, each with a probability of success (correct) given by p=0.5. 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) = ?
