Assume that random guesses are made for nine multiple choice questions on an SAT test, so that there are n = 99 trials, each with probability of success (correct) given by p = 0.35. Find the indicated probability for the number of correct answers.
Find the probability that the number x of correct answers is fewer than 44.

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual?
