Stephen does not like yogurt very much, but he loves

apples. Since both make a good snack, Stephen’s mom

makes a deal with Stephen. She will keep the refrigerator

stocked with 5 yogurts, 2 green apples, and 3 red apples

every day. Each day, Stephen will randomly pick a

snack. Use a tree diagram or area model to show all the

possible outcomes in the sample space. What is the

probability Stephen will not get three yogurts on three

consecutive days?
