What is the probability of getting a sum of 7 if two dice are tossed?
For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
When two dice are rolled what is the probability that the sum is either 7 or 11?
2 Answers. The probability is 25% .
What is the probability of getting a sum of 9 when two dice are rolled?
The probability of getting 9 as the sum when 2 dice are thrown is 1/9.
What is the probability of getting a sum of 11 if a pair of dice is tossed once?

When two dice are thrown simultaneously What is the probability?
We know that the total number of possible outcomes when two dice are thrown is =6×6=36. We know that the probability of any event is the ratio of the number of favourable outcomes and the number of possible outcomes.
How many ways can a sum of 2 or a sum of 10 be rolled with a pair of standard dice?
If you consider the chart on the webpage given, there are 36 combination of rolls you can get from two dice. When you consider the sum being 10, there are only 3 combinations. So, the probability of getting a 10 would be 3/36 = 1/12.
