Answer:
1/24
Step-by-step explanation:
So let's first find the total number of ways the pizza can be made.
2 types of crust
3 types of cheese
4 toppings
So if we choose crust 1, we have 3 options for cheese. For each of these options, we have 4 options for toppings. 4 x 3 will give us the number of topping-cheese combinations available, and likewise, we can apply this to the two crusts, getting 4 x 3 x 2, or 24.
Next, we will find the probability of choosing a thin crust with parmesan cheese and pepperoni. That's 1 crust, 1 cheese, and 1 topping, giving us 1/24 as this is a single combination.
(Probability of event)/(All possible events)
1/24
