Alejandria has four shirts and three pairs of pants. She says that she has seven possible combinations.

Answer: False, there are 12 possible combinations.

Step-by-step explanation:

Each pair of pants matches to each shirt.

She has 3 pairs of pants (1, 2, & 3) and 4 shirts (A, B, C, & D).

Here are all of the combinations:

1A 1B 1C 1D

2A 2B 2C 2D

3A 3B 3C 3D

There are 3 pants * 4 shirts = 12 different combinations
