The probability is 8/36 or 2/9

Probability that the sum is 6 = 5/36 Probability that the sum is 7 = 6/36

There is an approximately 8% chance of that, or 1 out of 12.

It is 15/36 = 5/12

If two dice are rolled, the probability that the sum of observed values is equal to 13 is zero. The sum of two dice can only lie between 2 and 12, inclusive.

The probability is 8/36 or 2/9

When rolling one die, the probability of getting a 4 is 1 in 6, or 0.1667. If two dice are rolled, you get two unrelated chances of rolling at least one 4, so the probability is 2 in 6, or 0.3333.

Two standard dice cannot have a sum greater than 12. The probability, then, of getting a sum greater than 15 is zero.

It is 15/36 = 5/12

5 out of 12

There are 36 permutations of two dice. Of these, 9 have a sum of 5 or 6, so the probability of rolling a sum of 5 or 6 on two dice is 9 in 36, or 1 in 9, or about 0.1111.

If two dice are rolled, the probability that the sum of observed values is equal to 13 is zero. The sum of two dice can only lie between 2 and 12, inclusive.

The probability is 35/36.

the probability is 1 out of 6

Probably.
