What is the probability of rolling an even number on 2 dice?
1. The probability of getting an even number at the first die is 1/2 (as the probability of even = the probability of odd = 1/2); 2. The probability of getting a total of 8 is 5/6^2, as there are 5 different favorable scenarios: (2,6), (6,2), (3,5), (5,3) and (4,4);
What is the probability of getting a sum of 2 when rolling 2 dice?
Two (6-sided) dice roll probability table
| 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 both dice showing an even number?
(a) At least one of the dice shows an even number? P(at least one is even) = 1 – P(both are odd). And the probability that the first die shows an odd number is 1/2, as is the probability that the second does.

| Outcome | Probability | Product |
|---|---|---|
| 5 | 1/6 | 5/6 |
| 6 | 1/6 | 6/6 |
| Total: | 21/6 |
What is the probability that the sum of the numbers on two dice is odd when they are rolled?
The odds of rolling an odd number from the sum of two rolls requires that we roll one even number from one die and an odd number from another die. The odds of this happening are 12.
What is the probability of rolling an odd number?
The probability when rolling a regular six-sided dice that the score is an odd number is three-sixths or three out of six. Both three and six are divisible by three. Therefore, this fraction could be simplified to one-half. Three divided by three is equal to one.
What is the probability of getting a number less than 2 or a prime number upon rolling a six-sided die?
Correct.In a six–sided die, the values greater than 4 is {5, 6}. Getting a number less than 2 can only be {1}. Since these events do not have any numbers in common, these are non-overlapping events.
What is the probability of rolling a sum of 12 with two dice?
Probabilities for the two dice
| Total | Number of combinations | Probability |
|---|---|---|
| 9 | 4 | 11.11% |
| 10 | 3 | 8.33% |
| 11 | 2 | 5.56% |
| 12 | 1 | 2.78% |
What is the probability of getting a sum of 8 in rolling two dice?
Probabilities for the two dice
| Total | Number of combinations | Probability |
|---|---|---|
| 8 | 5 | 13.89% |
| 9 | 4 | 11.11% |
| 10 | 3 | 8.33% |
| 11 | 2 | 5.56% |
What is the probability of getting a sum of 7 when two dice are thrown?
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 4 or an odd number?
There are two cases, one where you first get the four, or you get an odd then a four. The probability of just rolling a 4 first is 16. If you roll one odd number before the 4, that has a chance of 12∗16 Now, you can roll 2 or 6 infinitely many times and it won’t matter.

Is 1 a odd number?
An odd number is an integer when divided by two, either leaves a remainder or the result is a fraction. One is the first odd positive number but it does not leave a remainder 1. Some examples of odd numbers are 1, 3, 5, 7, 9, and 11. An integer that is not an odd number is an even number.
