Soffritto Italian Grill served 220 dinners last Saturday night. The Chef's Special was ordered by 15% of the customers. A random sample of 50 customer orders from that evening was selected. What is the probability that between 8 and 12 of these orders were the Chef's Special?

Question

Quizplus · Accepted Answer

This is a binomial probability problem where n = 50 (sample size), p = 0.15 (probability of ordering the Chef's Special), and we're looking for the probability of k being between 8 and 12. Using the binomial probability formula or a calculator with binomial probability functions, we find the cumulative probability of getting 8 to 12 orders of the Chef's Special, which is approximately 0.3912.
