In a simultaneous throw of a pair of dice, what is the probability of getting a total more than 8?

Solution

✅ Correct Option: 2

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 =6×6=36= 6 \times 6 = 36


All combinations where the sum is more than 8:

Sum =9= 9: (3,6), (4,5), (5,4), (6,3) → 4 ways

Sum =10= 10: (4,6), (5,5), (6,4) → 3 ways

Sum =11= 11: (5,6), (6,5) → 2 ways

Sum =12= 12: (6,6) → 1 way

Total favorable outcomes =4+3+2+1=10= 4 + 3 + 2 + 1 = 10


Probability =Favorable outcomesTotal outcomes= \frac{\text{Favorable outcomes}}{\text{Total outcomes}}

Probability =1036= \frac{10}{36}

Probability =518= \frac{5}{18}

Therefore, the probability of getting a total more than 8 is 518\frac{5}{18}.
