One can get a sum of 3 in two ways: (1,2) or (2,1). These are two of the 36 possible rolls, so the probability is 2/36 or 1/18 or 5.55% making the usual assumptions (unbiased dice, outcomes on the two die are independent). Answer is 2/36.
What is the probability of rolling 2 dice and getting a sum of 3?

What is the probability of you rolling a sum of 3?
We divide the total number of ways to obtain each sum by the total number of outcomes in the sample space, or 216. The results are: Probability of a sum of 3: 1/216 = 0.5% Probability of a sum of 4: 3/216 = 1.4%
What is the probability of getting sum 3 or 4 when two dice are rolled?
When we roll two dice, the possibility of getting number 4 is (1, 3), (2, 2), and (3, 1). So, The number of favorable outcomes = 3. Total number of possibilities = 36.
What is the probability of getting a total of 7 when rolling 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.
When two sided dice are rolled There are 36 possible outcomes?
Every time you add an additional die, the number of possible outcomes is multiplied by 6: 2 dice 36, 3 dice 36*6 = 216 possible outcomes.
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.
What is the probability of getting a sum of 20 when tossing 2 dice?
Answer Expert Verified
The maximum sum that we can get when we roll 2 dice is 12. So, the probability of getting 20 is obviously .
What is the probability of getting at most the difference of 3?
1/6 chance for each side, 1/36 to roll any one of those combinations. Multiply that chance by 3, for the 3 combinations we can roll to give us a difference of 3, and we get 3/36, or an 8.
