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 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)

No.
What are the chances of rolling an even number on a six sided dice?
there is exactly a 50% chance.
What is the mathematical probability for each number on a dice if you roll the dice fifty times?
If the dice is 6 sided, the chances of rolling each number is about 17% (100/6) If the dice is 4 sided, the chances of rolling each number is 25% (100/4) Similarly, 8 sided = 12.5% 10 sided = 10% 12 sided ≈ 8% 20 sided = 5%

What is the probability of rolling a seven on a dice?
0% probability
What is the probability of rolling a 5 on a six sided dice?
1 out of 6 chances
What is the probability of getting a number greater than four when rolling a dice?
When you throw a dice there is always 6 chances of getting a number; therefore the numbers greater that 4 are: 5 and 6 (2 options) in total there will be 2/6 chances will simplifies to 1/3
When rolling five dice what is the probability that all 5 dice will be the same number?
The probability of rolling the same number on five dice is (1/6)4, or about 0.0007716.
