DBA. How many ways are there to roll two distinct dice to yield a sum divisible by 3? Answer is 12.
When 2 dice are rolled find the probability of getting a sum that is divisible by 3?
There are 3×3=9 total possibilities for the two dice, which makes the probability of getting a multiple of three 3/9=1/3. Since there are 6×6=36 total dice rolls and 1/3 of those are a multiple of three, the number which are divisible by three is (1/3)(36)=12.
What is the probability of rolling two dice with a sum of 8?

What is the probability that a number is divisible by 3 or divisible by 4?
6/12 possibilities, so the answer is 1/2 probability that you’ll land on a number divisible by 3 or 4.
What is the probability of rolling a number divisible by 3?
When a fair die is thrown, the probability of getting each of the digit 1,2,3,4,5 and 6 is 16 . Of these, digits divisible by 3 are 3 and 6. Hence when you roll a fair die once, probability of getting a number divisible by 3 is 26 or 13 .
What is the chace of getting 7 or 11 with 2 dice?
What about 7 OR 11? There are 6 x 6 or 36 options, all are equally likely, 7 occurs 6 times, so the chances are 6/36 or 1/6. 11 occurs 2 times so chances are 2/36 or 1/18. 7 or 11 are 8 of the 36 options so 8/36 or 2/9.
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 probability of getting a sum of 20 when rolling to dice?
Step-by-step explanation: The maximum sum that we can get when we roll 2 dice is 12. So, the probability of getting 20 is obviously .
How many ways can we get a sum of 8 when two indistinguishable dice are rolled?
There are 36 possible combinations. 2. You can get an 8 with 6-2, 5-3, 4-4, 3-5 and 2-6.
