Question:
Bistro 65 is a chain of Italian restaurants with locations in Ohio and Kentucky. The Bistro 65 menu has four categories of entrees: Pasta, Steak & Chops, Seafood, and Other (e.g., pizza, sandwiches, etc.). Historical data for the chain show that the probability a customer will order an entrée from one of the four categories is .4 for Pasta, .1 for Steak & Chops, .2 for Seafood, and .3 for Other. A new Bistro 65 restaurant has just opened in Dayton, Ohio, and the following purchase frequencies have been observed for the first 200 customers.
Category Frequency
Pasta.........................................70
Steak & Chops.........................30
Seafood....................................50
Other........................................50
