Final answer:
The question is about probability and combinations in mathematics, where the total number of possible outfits Matias can wear is calculated by multiplying the choices for each article of clothing, resulting in 12 possible outfits.
Step-by-step explanation:
The question posed relates to the mathematics subject area and involves the use of probabilities and combinations to determine the outcomes of Matias's random selection of clothing in the dark. Matias has three choices for a shirt, two choices for a pair of pants, and two choices for shoes. To find the total number of outfits Matias could potentially wear, we calculate the product of the number of choices for each article of clothing.
- Shirts: Green, Red, Yellow (3 choices)
- Pants: Black, Blue (2 choices)
- Shoes: Checkers, Red (2 choices)
By multiplying the number of choices for each category, we obtain the total number of possible outfits:
3 (shirts) x 2 (pants) x 2 (shoes) = 12 possible outfits.
This is a simple yet classic example of a combinatorial problem where we are interested in the number of ways to combine different choices.
