The local ice cream stand offers three flavors of soft-serve ice cream: vanilla, chocolate, and strawberry: two types of cone: sugar and wafer: and three toppings: sprinkles, nuts, and cookie crumbs. If Dawn does not order vanilla ice cream, how many different choices can she make that have one flavor of ice cream, one type of cone, and one topping?

Hello, CamileDanica!

The local ice cream stand offers three flavors of soft-serve ice cream: vanilla, chocolate, and strawberry:
two types of cone: sugar and wafer; and three toppings: sprinkles, nuts, and cookie crumbs.
If Dawn does not order vanilla ice cream, how many different choices can she make
that have one flavor of ice cream, one type of cone, and one topping?

Since she does not order vanilla, she has 2 choices of flavor.
She has 2 choices of cones and 3 choices of toppings.'

Therefore, she has: .\(\displaystyle 2 \times 2 \times 3 \:=\:12\) .possible choices.
