Faith is a 95% free throw shooter. At practice, each player shoots 20 free throws. Let X = the number of free throws Faith makes out of 20 shots. (round all answers to 3 decimal places). Calculate the mean of X. Calculate the standard deviation of X. Use the binomial probability formula to find P(X = 19). Her coach says that he will let the team out of practice early if Faith makes 18 or more free throws. What is the probability that practice ends early?
