Answer the following:

(A) Find the binomial probability P(x = 6), where n = 15 and p = 0.60.
(B) Set up, without solving, the binomial probability P(x is at most 6) using probability notation.
(C) How would you find the normal approximation to the binomial probability P(x = 6) in part A? Please show how you would calculate µ and ? in the formula for the normal approximation to the binomial, and show the final formula you would use without going through all the calculations.
