Question 342473
The first scoop can be one of 10 flavors.
The second scoop can be one of 10 flavors.
So there are {{{10*10=100}}} ways to make two scoops.
As long as you are fine with the idea that a scoop of (let's say) chocolate on top of vanilla is a different cone than a scoop of vanilla on top of chocolate, then the answer is 100.
If you think a cone with vanilla and chocolate is the same regardless of which scoop is on top, then look here for the correct formula. See the combination section

I would say 100
