Question

A restaurant sells combo meals in the sizes of small, medium, or large. The combo comes with either a hamburger or chicken strips. It also includes either French fries or onion rings.

Draw a tree diagram to represent the possible outcomes of ordering a combo meal.
How many outcomes include onion rings?

Answer 1

6 outcomes

Explanation:

A tree diagram is a diagram that helps calculate the number of possible outcomes of an event or problem, and to cite those potential outcomes in an organized way.

A restaurant sells combo meals in the sizes of small, medium, or large (3 outcomes in total).

The combo comes with either a hamburger or chicken strips (two outcomes for each one previous outcome - 6 outcomes in total).

Combo also includes either French fries or onion rings (two outcomes for each one previous outcome - 12 outcomes in total).

Onion rings include half of all outcomes - 6 outcomes
