Answer the following:
(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 ยต and σ in the formula for the normal approximation to the binomial, and show the final formula you would use without going through all the calculations.

Question 11
Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to find the probability of x successes given the probability p of success on a single trial. Round to three decimal places. n = 5, x = 2, p = 0.70
