What is the probability of rolling a sum greater than or equal to four?
1 Expert Answer So in a single roll the probability of getting a number greater than 4 is 2/6 = 1/3.
What is the probability of rolling a number greater than or equal to five?
The numbers greater than 5 are 6 . The numbers less than 3 are 2,1 . So the numbers greater than 5 OR less than 3 are the union of the two sets or 6, and 2,1. The probability of rolling one of these numbers is 36=12 or 50\% .
What is the probability of rolling a number greater than 3?
Probability of rolling more than a certain number (e.g. roll more than a 5).
| Roll more than a… | Probability |
|---|---|
| 2 | 4/6 (66.67\%) |
| 3 | 3/6 (50\%) |
| 4 | 4/6 (66.667\%) |
| 5 | 1/6 (66.67\%) |
What is the probability of rolling doubles or a sum of 8?
There are 36 outcomes in total. Five of them (2,6), (3,5), (4,4), (5,3) and (6,2) result in sum 8. So, assuming all outcomes are equiprobable, the answer is 5/36.
What is the probability of spinning a number greater than 1?
The probability of spinning a number greater than 1 is 4 / 5 .
What is the probability of rolling 8 on 2 dice?
5/36
6 Sided Dice probability (worked example for two dice). Two (6-sided) dice roll probability table….Two (6-sided) dice roll probability table.
| Roll a… | Probability |
|---|---|
| 8 | 5/36 (13.889\%) |
| 9 | 4/36 (11.111\%) |
| 10 | 3/36 (8.333\%) |
| 11 | 2/36 (5.556\%) |
How do you find the probability of rolling a single 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. In other words, the probability P equals p to the power n, or P = pⁿ = (1/s)ⁿ.
What is the probability of rolling a 15 on a dice?
If we consider three 20 sided dice, the chance of rolling 15 on each of them is: P = (1/20)³ = 0.000125 (or P = 1.25·10⁻⁴ in scientific notation). And if you are intereseted in rolling the set of any identical values, simply multiply the result by the total die faces: P = 0.000125 * 20 = 0.0025.
What are the odds of rolling more than 6 on average?
In other words, you have a 72.22\% chance (13 out of 18) of rolling greater than or equal to 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.
