The ice cream shop offers chocolate, vanilla, and strawberry ice cream.  You can then choose to have sprinkles, chocolate pieces, or walnuts as a topping.  Last, you must decide if you want whipped cream or not.  Create a tree diagram to show all of the possible ice cream combinations that you can have at the ice cream shop. I got 21 as an answer. Am I correct?

Multiply the variations of ice cream with the variations of topping and whipped cream. I guess that you can also have an ice cream without any topping. So that's 3 times 4 times 2 = 24.

The colours represent the same item on each branch.

3 different flavours of ice cream

4 different toppings, including no topping at all

2 choices of cream: with or without
