Hey there! I'm happy to help!
Let's pretend that we are building a small sundae. We have 3 choices of ice cream flavors.
Now, we want to pick a topping. We have 4 choices here.
After we choose a topping, we can pick another. We only have 3 choices now because we need different toppings, and we already used one.
We want to find how many possible combos we can make. What we do is multiply all of these numbers of choices, and this will show us how many possible sundaes there are.
3×4×3=36
Therefore, there are 36 different sundaes that can be made.
Have a wonderful day! :D
