The question involves a scenario where Francisco and Juliana are playing with two 12-sided dice, one red and one green. The rules specify that:

- Points from the red die are **negative**.
- Points from the green die are **positive**.

Francisco rolls and gets:
- **12 on the red die**, which would count as **-12 points**.
- **9 on the green die**, which would count as **+9 points**.

To determine Francisco's total points, we add the values from both dice:
\[
-12 + 9 = -3
\]

Thus, Francisco's total score is **-3 points**, and the correct answer is B. 

Would you like a detailed explanation or have any further questions?

Here are some related questions for practice:
1. What would be the total points if Francisco rolled a 7 on the red die and 5 on the green die?
2. How would the game change if points from the red die were doubled?
3. If Juliana rolled a 10 on both dice, what would be her score?
4. Can the total points ever be zero in this game? If so, how?
5. How does changing the number of sides on the dice affect the possible outcomes?

**Tip:** When solving problems with both positive and negative values, always carefully distinguish which numbers contribute negatively and which positively.

Francisco y Juliana están jugando con dos dados de doce caras, uno rojo y uno verde. El juego consiste en lanzar los dos dados y sumar sus puntos, los puntos del dado rojo son negativos y los puntos del dado verde son positivos. Si Francisco lanza y obtiene 12 en el dado rojo y 9 en el dado verde, ¿cuántos puntos obtiene?
