# Quantitative Methods- Probability Problem

4) 55% of a restaurant's orders are from customers eating in the restaurant and 45% from the drive through window. 65% of the orders from the customers eating in the restaurant are from food and 35% from drinks. 79% of the drive through orders are from food and 21% from drinks. Use this information to find the following probabilities.

a)That an order is a window order (3 points).

b)That an order is a drink order given that it is a window order (3 points).

c)That an order is a window order and a drink order (5 points).

d) Suppose it known that an order is a drink order. Use the tabular form of Bayesâ?? theorem to find the probability that it is a window order (10 points).
