2 | 1/36 (2.778\%) |

What is the probability of getting a 5 when rolling two dice?
The chances of getting a 5 on your first die are 1 in 6. If you do, the chances of NOT getting a 5 on the second die are 5 in 6. 1/6*5/6=5/36 of the time you’ll get one 5 this way. If you don’t get a 5 on the first die (that’s a 5/6 chance) then the chances of getting a 5 on the second die are 1 in 6.

What is the probability of rolling the sum of two dice?
The combinations for rolling a sum of seven are much greater (1 and 6, 2 and 5, 3 and 4, and so on). To find the probability that the sum of the two dice is three, we can divide the event frequency (2) by the size of the sample space (36), resulting in a probability of 1/18. 3. Two six-sided dice are rolled.
How do you find the probability of rolling a die?
To determine the probability of rolling any one of the numbers on the die, we divide the event frequency (1) by the size of the sample space (6), resulting in a probability of 1/6. Rolling two fair dice more than doubles the difficulty of calculating probabilities. This is because rolling one die is independent of rolling a second one.
What is the probability of rolling a 2 in blackjack?
Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6 and so on for 3, 4, 5, and 6.
What is the probability of getting 7 on a 10-sided die?
There is a simple relationship – p = 1/s, so the probability of getting 7 on a 10 sided die is twice that of on a 20 sided die. The probability of rolling the same value on each die – while the chance of getting a particular value on a single die is p, we only need to multiply this probability by itself as many times as the number of dice.
