Ann is the owner of Crazy Pizzas, a small company that delivers pizza from two locations. The South site handles 40% of the orders while the North location delivers the remaining orders. In its promotional materials, Crazy Pizzas strives to deliver all orders within 45 minutes. Historically, the North location has experienced 5% of its orders taking longer than 45 minutes to deliver. The South store has been late on 15% of its orders. Ann has just spoken to a customer whose order was delivered 1 hour after it was placed but did not remember from which location the order originated. What is the probability that the late order came from the South store?
