Show Answer Key & Explanations Step-by-step solution for: Probability

▼

Let’s solve this step by step.

We are told:
- You choose 1 burger, 1 side serve, and 1 drink.
- Burgers available: beef, chicken, fish → that’s 3 choices
- Side serves: fries, salad → that’s 2 choices
- Drinks: cola, juice → that’s 2 choices

To find the total number of possible combinations (outcomes), we multiply the number of choices for each category:

→ 3 burgers × 2 sides × 2 drinks = ?

First, 3 × 2 = 6
Then, 6 × 2 = 12

So, there are 12 possible outcomes.

This matches what the tree diagram shows — it branches out to 12 final paths.

Final Answer:
12
