And the rest of the question?

To create a tree diagram showing the possible outcomes for a 1 topping pizza at Pepi's Pizza, we can follow the steps below:

Step 1: Start with a central node labeled "Crust Type" with two branches: Thin Crust and Thick Crust.

Step 2: From the Thin Crust branch, draw four additional branches labeled with each available topping: Mushrooms, Onions, Pepperoni, and Sausage.

Step 3: Repeat step 2 for the Thick Crust branch, drawing the same four additional branches labeled with each available topping: Mushrooms, Onions, Pepperoni, and Sausage.

Step 4: The final tree diagram will have two levels. The first level represents the crust type, and the second level represents the toppings. Each topping branch extends from both the Thin Crust and Thick Crust branches.

Here is an example of a tree diagram showing the possible outcomes for a 1 topping pizza at Pepi's Pizza:
