<h3>Answer: C) 12</h3>

======================================================

Explanation:

There are 3 colors of sweaters {red, green, purple} and 2 colors of skirts {tan, black}

So far there are 3*2 = 6 different outfit combinations. Imagine a table with 3 rows representing the sweater colors and 2 columns representing the skirt colors. There would be 6 cells in the table representing each possible combination. One cell would have (red sweater, tan skirt) for instance.

For each of those 6 combinations, we also have 2 shoe colors. So overall we have 6*2 = 12 outfit combinations

The tree diagram is shown below. Note how there are 3*2*2 = 12 different paths to follow.

\left( \cfrac{2}{5} \right)^{-2}\implies \left( \cfrac{5}{2} \right)^{+2}\implies \left( \cfrac{5^2}{2^2} \right)\implies \cfrac{25}{4}\implies 6\frac{1}{4}$
