A) Find the binomial probability P(x = 5), where n = 12 and p = 0.70.

B) Set up, without solving, the binomial probability P(x is at most 5) using probability notation.

C) How would you find the normal approximation to the binomial probability P(x = 5) in part A? Please show how you would calculate u and standard deviation in the formula for the normal approximation to the binomial, and show the final formula you would use without going through all the calculations.
