Answer: The probability of rolling two dice and getting a sum of 4 is 1/12.
When two dice are rolled what is the probability that one die is a 4 Given that the sum of the two die is nine?
The probability is 3+4+1 over 36. That’s 8/36, simplified to 2/9.
What is the probability of rolling all ones with 4 dice?
There are permutations of rolls. Out of all those permutations, match the criteria your looking for, so there are six permutations that would be acceptable. 6 / (6 x 6 x 6 x 6) = 1 / (6 x 6 x 6) = 1 in 216. The probability that 4 dice show the same number is (1/n) ^4, where n equals the number of sides on a given die.
What is the probability of getting a sum of 6?

How do we calculate probabilities?
How to calculate probability
- Determine a single event with a single outcome.
- Identify the total number of outcomes that can occur.
- Divide the number of events by the number of possible outcomes.
What is the probability of not rolling any 6’s in four rolls of a balanced die?
a) Consider the complement problem, there is a 5/6 probability of not rolling a six for any given die, and since the four dice are independent, the probability of not rolling a six is (5/6)4 = 54/64 = 625/1296.
