In Example 5.4 on page 209, you and two friends decided to go to Wendy’s. Now, suppose that instead you go to McDonald’s, which recently filled approximately 92.2% of the orders correctly. What is the probability that

a. All three orders will be filled correctly?

b. None of the three will be filled correctly?

c. At least two of the three will be filled correctly?

d. What are the mean and standard deviation of the binomial distribution used in (a) through (c)? Interpret these values.

e. Compare the result of (a) through (d) with those of Burger King in Problem 5.16 and Wendy’s in Example 5.4 on page 209.
