DECISION ANALYSIS, BAYES THEOREM: Find the solution to the problem below:
Big Pound Pizzas delivers large pizzas from two different shop locations. The Dayton site handles 40% of the total orders while the Harrisonburg site delivers the remaining orders. The Big Pound Pizza ads in the Harrisonburg Daily News Record claim that the shops deliver all such orders in an eight-mile radius within 45 minutes. Historically, the Harrisonburg site has experienced 5% of its orders taking longer than 45 minutes. The Dayton shop has been late on 15% of its orders. The general manager has just spoken to a customer whose order was delivered one hour after it was placed but did not remember which location the order originated. What is the probability that the late order came from the Dayton pizza shop?
