This is for fun. Any genius' out there lol? Suppose a basketball player, Player A, made 80% of her free throw attempts last season and that she continues to shoot free throws at the same rate. Assume that free throw attempts are independent. Let the random variable X be the number of free throws that player A makes in her next 15 attempts. a) What is the distribution of X? b) Find the mean and standard deviation of X. c) Find the probability that player A makes exactly 10 free throws. d) Find the probability that player A makes at least 8 free throws.
You will find the answer by understanding the fundamentals of probability. http://dipeco.economia.unimib.it/persone/stanca/Economet/stat_app_wool.pdf Please look over that PDF. If you are having a hard time and want just the answer then PM me, but it is rather simple and you need to get a grasp on these basics or you will never make it as these are the fundamentals.
Binomial distribution mean = 12 std dev = 1.54919..... exactly 10 = 0.103182294319104 atleast 8 = 0.19999999999999996 Sorted ... If this is for homework you really should learn it.
