For normal dice, and assuming "combined" refers to the sum, the answer is 7.

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.
With two normal six-sided dice, the maximum sum can only be 12 (6 x 2 dice), so there is zero probability of rolling a sum that adds to 16.

there is a 1 to 5 probablilty that you will roll the sum of 6 with two dice.
With two normal six-sided dice, the maximum sum can only be 12 (6 x 2 dice), so there is zero probability of rolling a sum that adds to 16.
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.
Zero is the probability of rolling a sum of 15 on two fair dice; the maximum value is 12.
The two dice sum of 4: 1,3 2,2 3,1 = 3 in 36 = 1 in 12
