Assuming it is a normal fair cube, it is 1/6.

If two twelve side fair dice are rolled, there are 144 possible outcomes. Of those 144 outcomes, there are four (1-4, 2-3, 3-2, and 4-1) that add up to five, So the probability of rolling a sum of five is 4 in 144, or 1 in 36.

There are 36 possible outcomes when we roll a pair of dice. Rolling a five can be done the following ways: 3-2, 4-1, 2-3 and 1-4. That's four ways to roll a five with one roll of the dice. The odds of rolling a five are 4 in 36, or 1 in 9. That makes the probability of rolling a five equal to 0.11111....We know that the probability of something is a ratio of the number of times it can be done to the total number of things that are possible. Probabilities range from zero to one, inclusive. If something has a probability of zero, it cannot happen. Like rolling a 13. A 13 cannot be rolled with one roll of a pair of standard dice. Thus the probability of rolling a 13 is zero, as it cannot happen.If something has a probability of one, it must happen. Like the probability of rolling an odd or an even number with one roll of a pair of dice. Since any number we roll must be either odd or even, then the probability of rolling an odd or an even number with one roll of a pair of dice is one. An odd or an even number must turn up, and that is why the probability of rolling an odd or an even number with one roll of the dice is one. Lastly, we've seen that the probability of rolling a given number with one roll of the dice is the number of times that number might appear divided by the total number of possibilities that might appear.

It is going to be 1 over 6 because there is only 6 numbers on a dice and only one 5.

The answer depends on what numbers are on the faces of the dice.

Fair dice are dice that are not weighted on one side to make a particular number more probable than the others. The probablity of a four on one dice is 1/6. The probability of a four showing on either or both of two dice is 1/6 + 1/6 = 1/3 (Note this is different from rolling a total score of four with two dice which can be achieved with 1+3, 3+1 or 2+2 which is 3 out of 36 combinations or 3/36)

If using regular dice, the probability is 0 since the minimum sum from four dice is 4.

The probability of rolling a four on a single roll of a fair die is 1/6. So the expected number of 4s in 450 rolls is 450*1/6 = 75.

It is 0.375

It is going to be 1 over 6 because there is only 6 numbers on a dice and only one 5.

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.
