What is the probability of rolling a two and a two when two fair number cubes are rolled?
33/36 = 11/12 or approximately 91.67%. , Math is fun. Two number cubes are rolled.
What is the probability of rolling two number cubes?
1 Expert Answer The probability that event A will happen is 2 out of 6 (since 2 and 4 are two numbers out of 6 possible numbers) or 1/3.
What are fair number cubes?
A fair number cube is a cube with six sides, each containing a different number.
When rolling a set of two fair number cubes What is the probability of rolling a sum greater than 7?
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 of nine when two fair number cubes are rolled?
As in all there are 6⋅6=36 options, probability is 436 or 19 .
What is the probability of rolling a 2 or a 4 with a fair number cube?
What is the probability of rolling a 2 or 4 on a number cube?
| Roll a… | Probability |
|---|---|
| 2 | 1/36 (2.778%) |
| 3 | 2/36 (5.556%) |
| 4 | 3/36 (8.333%) |
| 5 | 4/36 (11.111%) |
What is the probability of rolling a sum of 10 using two number cubes?
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.
What are the odds of rolling a sum of 9 using two number cubes?
When a dice is rolled there are different ways in which 9 can be obtained, which are (3,6) or (4,5) or (5,4) or (6,3) i.e. 4 options. As in all there are 6⋅6=36 options, probability is 436 or 19 .

What’s the probability of rolling a 7 on two dice?
Probabilities for the two dice
| Total | Number of combinations | Probability |
|---|---|---|
| 6 | 5 | 13.89% |
| 7 | 6 | 16.67% |
| 8 | 5 | 13.89% |
| 9 | 4 | 11.11% |
What is the probability of rolling a sum of 7 and 11?
If you’re still in the ball game, your chance of getting the second roll you need for an 11 is again 16, so the total chance that you will roll an 11 is 13⋅16=118. Adding these two independent probabilities, the chance of rolling either a 7 or 11 is 16+118=29.
