A pizza restaurant sells two different crusts (regular and thin-crust) and three different toppings (pepperoni, sausage, and bell peppers). Draw an area model to represent the situation. Then use your area model to find the probability a random customer in the pizza restaurant would order a thin-crust pizza with pepperoni or sausage.

**Problem Description:**

A pizza restaurant sells two different crusts (regular and thin-crust) and three different toppings (pepperoni, sausage, and bell peppers). Draw an area model to represent the situation. Then use your area model to find the probability a random customer in the pizza restaurant would order a thin-crust pizza with pepperoni or sausage.

**Solution Steps:**

1. **Create an Area Model:**
   - Draw a grid with two rows and three columns.
   - Label the rows with the two crust options: "Regular" and "Thin-crust."
   - Label the columns with the three topping options: "Pepperoni," "Sausage," and "Bell Peppers."

2. **Calculate the Total Options:**
   - There are a total of 2 crusts x 3 toppings = 6 combinations.

3. **Identify the Favorable Outcomes:**
   - Identify the thin-crust pizzas with pepperoni.
   - Identify the thin-crust pizzas with sausage.
   - There are 2 favorable outcomes (thin-crust with pepperoni, thin-crust with sausage).

4. **Calculate the Probability:**
   - Probability of selecting a thin-crust pizza with pepperoni or sausage = favorable outcomes / total outcomes = 2/6 = 1/3.

The probability that a random customer would order a thin-crust pizza with pepperoni or sausage is 1/3.
