If the probability that a customer will stay in the restaurant to eat is .60, use the Binomial Probability function to determine the probability that 3 out of 4 customers entering the restaurant to place an order will eat their food in the room:
Using the Binomial Probability table, calculate the probability that at least 12 out of 18 customers entering the restaurant to order will eat their food in the dining room:
If the mean arrival rate for customers during the lunch rush is 6 every 10 minutes, use the Poisson distribution function to determine the probability that exactly 7 customers arrive in a 10 minute period.
