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.

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.
