Question
A vendor specializing in outdoor gear offers customers three ways to place orders for home delivery.
Customers can place orders either in the store, online, or via telephone using a catalog. Of the orders,
three-quarters are made online with one-eighth each made in stores or via telephone. Of the online
orders, 30% are only for clothing, 30% are only for camping supplies, and 40% are for both. For orders
placed in the store, all are for clothing (to order a size that is not in stock). Among orders placed via
telephone, 50% are only for clothing, 20% are only for camping supplies, and 30% are for both.
Answer parts (a) and (b).
(a) Organize these probabilities as a probability table.
