Question

Most Miami Beach restaurants offer “early-bird” specials. These are lower-priced meals that are available only from 4 to 6 p.m. However, not all customers who arrive between 4 and 6 p.m. order the special. In fact, only 70% do.
a. Find the probability that of 80 customers between 4 and 6 p.m., more than 65 order the special.
b. What is the expected number of customers who order the special?
c. What is the standard deviation?
