When a pair of dice are thrown simultaneously the maximum sum possible is 12.The possible cases of getting a sum of 9 are:
So a total of 4 cases are possible
The possible cases of getting a sum of 10 are:
So a total of 3 cases are possible
The possible cases of getting a sum of 11 are:
So a total of 2 cases are possible
The possible cases of getting a sum of 12 are:
So a total of 1 case is possible.
Total number ways of getting a sum of 9 or more = 4 + 3 + 2 + 1 = 10 ways
Total outcomes when two dice are rolled simultaneously = 6 * 6 = 36 ways
Probability of getting a sum of 9 or more = Expected number of outcomes/ Total outcomes
