We have a probability of 1/6 that the first die rolls 2, and a probability of 1/6 that the second die rolls 2, thus making a combination (2,2) with the probability 1/36.
What is the probability of rolling two dice and getting a sum of 2?

What is the probability of rolling 2 dice and getting a sum of 9?
When 2 dice are thrown, the probability of the sum being 9 is 1/9.
What is the probability of getting a sum of 7 with two dice?
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.
What is the probability of rolling a sum less than 10?
That totals 8 combination out of 36 that could be ten or higher, so 8/36= 2/9. since I wanted less than ten 1-(2/9) = 7/9 probability of getting less than 10.
What is the probability of rolling a sum of 5 with four dice?
The only way to get a sum of 5 is to get three 1’s and one 2. So there are 4 ways to get that 2 with the other three 1’s, and a sum of 5. There are 6 ways each die can land so there are 6^4 or1296 ways for the dice to land. So the probability is 5/1296.
What is the probability of rolling a sum of 7 and 11?
What is the probability that the sum will be a 7 or 11? There are 36 possible outcomes for the two dice. So, the probability is 8/36 = 2/9.
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.
