What is the probability of getting a sum 9 from two throws of a dice?

  • A.1/6
  • B.1/8
  • C.1/9
  • D.1/12

Answer: C

Two throws give 36 outcomes. Those summing to 9 are

\[ (3,6),\ (4,5),\ (5,4),\ (6,3) \]

\[ P = \frac{4}{36} = \frac{1}{9} \]

Order matters, so \( (3,6) \) and \( (6,3) \) count separately.
