Question

Two dice are rolled simultaneously. What is the probability that the sum of numbers on dice is 9?

• A. 1/9
• B. 1/2
• C. 1/4
• D. 1/6

Hint:

To solve dice-sum problems quickly, memorize this pattern for rolling two dice:
- Sum of 2 or 12 \(\rightarrow\) 1 way
- Sum of 3 or 11 \(\rightarrow\) 2 ways
- Sum of 4 or 10 \(\rightarrow\) 3 ways
- Sum of 5 or 9 \(\rightarrow\) 4 ways (as in this question)
- Sum of 6 or 8 \(\rightarrow\) 5 ways
- Sum of 7 \(\rightarrow\) 6 ways
This symmetrical pattern allows you to find favorable outcomes instantly.
