There are 36 permutations of two dice. Of these, six have a sum of seven. The probability, then, of rolling a seven on two dice is 6 in 36, or 1 in 6, or about 0.1667.
It does not matter if two dice are rolled one time, or if one die is rolled two times. The probability of rolling a sum of 7 is still about 0.1667.
The first thing to do is to identify all possible combinations which could give the sum of 7. These are: 6 and 1, 5 and 2, 4 and 3, 3 and 4, 2 and 5, and 1 and 6.
Thus there are 6 possible combinations.
For each of these combinations, the probability of getting the 1st number correct is 1/6 and the probability of getting the second number correct is 1/6, and so the overall probability of the combination is 1/36
There are 6 ways to get 7 though so 6x 1/36 = 1/6
Which means the probability that 2 dice rolls will add up to 7 is 1/6

What is the chances of Rolling a 3 or 4 from two dice?
Assuming you are rolling a six-sided dice, it is 1/3 for one dice and 2/3 for two dice.
What are the chances of rolling a 6 with a dice?
A 1 in 6 chance.
Is rolling an even number on a number cube an outcome or an event?
Rolling a dice and getting an even number is an outcome. It is the result of rolling a dice.
If you had 2 dice what is the probability of rolling a 4?
4 out of 12 chances if each dice had 6 sides. 2 out of 6 chances to simplify it.
What is the probability of rolling a 4 or 5 on a six sided cube?
The chance of rolling a certain number on a dice is 1/6, so the chance of rolling a 4 OR 5is 2/6. But if you have two dice you have the most chance of rolling a seven (6/36 or 1/6)
