What is the probability that you would obtain a sum of 7 or a sum of 11 on the first roll?
For example, since a 7 or an 11 is a winner on the first roll and their probabilities are 6/36 and 2/36, the probability of winning on the first roll is 6/36+2/36=8/36.
What is the probability of rolling a 7 or 8?

What is the probability of rolling a total of 7 with two dice at least once in 10 rolls?
With the help of a calculator we find that we will not get a total of 7 on any of the first 10 rolls approximately 16.15% of the time. This implies that we will get a total of 7 on at least one of the first 10 rolls 100%−16.15%=83.85% of the time.
What is the probability of rolling a sum larger than 10?
Since there are a total of 6 x 6 = 36 outcomes, then the probability that the sum will be greater than 10 is 3/36 = 1/12.
When two dice are rolled what is the probability of getting a sum greater than 9?
So probability of getting a sum greater than 9 is= 6/36=1/6 Ans.
