Does this problem fall into Combinations and Permutations easy question?

Sorry I have this topic into the wrong forum almost close to probability and statistics maybe.

I added a screen shot of the problem what would the process steps and answer be?

There are
$\begin{pmatrix}5 \\ 2 \end{pmatrix} = 10$ ways to pick two flavors of ice cream

then each pair can have one of 3 cone types and (I'm assuming) one of 3 topping types.

This results in

$(10)(3)(3) = 90$ different cones using two flavors of ice cream.
