To solve this problem, we can use the fundamental principle of counting.

Keisha has:

• 2 choices for shirts,
• 2 choices for pants, and
• 3 choices for caps.

The total number of different outfits she can make is calculated by multiplying the number of choices for each item:

$2 \times 2 \times 3 = 12$

So, Keisha can make 12 different outfits.

Would you like further explanation or have any questions?

Here are some related questions for further practice:

1. What if Keisha had 4 shirts instead of 2? How many outfits could she make then?
2. How would the total number of outfits change if she had only 1 cap?
3. If Keisha adds a pair of shoes with 2 options, how many total outfits would she have?
4. What if Keisha had 3 shirts, 3 pants, and 3 caps—how many outfit combinations would be possible?
5. How does the fundamental principle of counting help in calculating combinations in larger sets?

Tip: When faced with multiple independent choices, multiply the number of choices for each category to find the total possible combinations.
