9.  Given the length an athlete throws a hammer is a normal random variable with mean 60 feet and standard deviation 3 feet, what is the probability he throws it between 54.9 feet and 64.5 feet?

10. If x is a binomial random variable where n = 100 and p = 0.3, find the probability that x is less than or equal to 20 using the normal approximation to the binomial.
