Betty is allergic to milk products. She discovers that 40% of the food items available in the school cafeteria contain milk products. She wants to know the odds of the cafeteria serving three meals in a row containing milk products so she can decide whether she should bring lunch from home. How can she simulate this situation to find the relative frequency?

The ratio of food items containing milk products to those without milk is 40:60 or 2:3. So Betty's simulation should have a multiple of 5 possible outcomes. She can model this situation using a 5-section spinner with 2 sections representing items containing milk and three sections representing items without milk. To find the odds of the cafeteria serving 3 meals in a row containing milk, spin the spinner 3 times. If all 3 spins land on sections representing food items that contain milk, it would mean the cafeteria would serve 3 meals in a row containing milk. To find the relative frequency of the event, Betty needs to perform the simulation multiple times.
