In a simultaneous throw of a pair of dice, what is the probability of getting a total more than 8?
In a simultaneous throw of a pair of dice, what is the probability of getting a total more than 8?
Solution
When throwing two dice simultaneously, the goal is to find the probability that the sum of both dice is more than 8.
More than 8 means: 9, 10, 11, or 12
When throwing 2 dice:
- First die can show: 1, 2, 3, 4, 5, or 6 (6 options)
- Second die can show: 1, 2, 3, 4, 5, or 6 (6 options)
Total possible outcomes
All combinations where the sum is more than 8:
Sum : (3,6), (4,5), (5,4), (6,3) → 4 ways
Sum : (4,6), (5,5), (6,4) → 3 ways
Sum : (5,6), (6,5) → 2 ways
Sum : (6,6) → 1 way
Total favorable outcomes
