You can roll (3,6), (4,5), (5,4), or (6,3). So that's four possibilities out of 36. So 4/36 or 1/9.

When rolling a pair of fair dice what is the probability that the sum of the dice on one roll will be seven?
It is 6/36 = 1/6.
If you roll a fair six-sided die and a fair four-sided die what is the probability that the dice add to 6 or higher?
The answer depends on what numbers are on the faces of the dice.
If you roll two fair six sided dice what is the probability that both dice show an odd number?
There are 6 × 6 = 36 possible outcomes There are 3 odd numbers, so there are 3 × 3 = 9 results that are a success → probability of both dice showing an odd number = 9/36 = 1/4
If you roll a number cube twice what is the probability of rolling a 6 and a 2?
Assuming that a dice roll is purely random, there is a 1 in 6 probability of landing on any number. Since the second roll depends on the probability of the first, they factor together: First Roll: 1/6 Second Roll: (1/6)(1/6) = 1/36 If you were rolling both dice at once, however, the math would be completely different.
A pair of dice are rolled What is the probability sum 12?
There is one way to roll a sum of 12. There are 36 different outcomes from rolling a pair of dice. Therefore, the probability is 1/36 ~= 0.0278 = 2.78%
If you roll two fair dice what is the probability you will roll a sum of nine or higher?
50%
When you roll two dice what is the probability their sum is 2?
For a single roll of a pair of fair dice, the answer is 1/36.
What is the probability that you roll a sum of 8 when you roll two fair dice?
6:5
If you roll four fair dice what is the probability the sum will be an odd number?
The probability is 1/2.
What is the probability you will roll a 3 and a 4 on 2 dice at the same time?
Assuming they are fair, regular dice, the probability is 1/18.
What is the probability that you roll a square number when you roll an ordinary fair 6 sided dice?
It is 1/3.
What is the probability of rolling a 5 on a dice?
It is 1: if you roll the die often enough. On a single roll of a fair die, the probability is 1/6.
What is the probability of scoring 11 when you roll two dice?
Assuming they are fair dice that are numbered 1 to 6, the probability is 2/36 = 1/18
What is the probability of rolling an even number with 3 dice?
With one roll of three dice, the probability is 7/8.
What is the probability of getting less than 6 when you roll a fair dice?
It is 5/6.
When rolling a pair of fair dice what is the probability that the sum of the dice on one roll will be seven?
It is 6/36 = 1/6.
What is the probability of not rolling a sum of 2 with two fair dice?
If you roll them often enough then the probability is 0. For just one roll, the probability is 35/36.
