Only 3 out of the possible 36 combinations turned out to have a sum of 4. So that is 1/12
The faster mental way:
You know a standard dice has 6 sides.
In this problem, there are two die. So that means you have to multiply 6 x 6. That is 36.
So there are 36 possible outcomes.
You know 1 + 3 = 4, 3 + 1 = 4, and 2 + 2 = 4. Those are the only 3 equations that have all positive numbers that have a sum of 4 (Zero is not positive nor negative).
You have your answer. 3/36. In simplest form, it is 1/12.

What is the probability of not rolling sum of 6 with two fair dice?
The probability of not rolling a sum of six with two fair dice is 1 minus the probability of rolling a sum of six. There are 36 permutations of rolling two dice. Of these, five sum to six, 1+5, 2+4, 3+3, 4+2, and 5+1. The probability, then of rolling a sum of six is 5 in 36. The probability, then of not rolling a sum of six is 31 in 36, or about 0.8611.
What is the probability of rolling a sum of 15 on two fair dice?
Zero is the probability of rolling a sum of 15 on two fair dice; the maximum value is 12.
When two dice are rolled what is the probability of not getting a sum of 12?
The probability of rolling 12 with 2 dice is 1 in 36. The probability of not rolling 12 with 2 dice is 35 in 36.

What is the probability of rolling a sum of 11 with 2 dice?
The probability of rolling a sum of 11 with 2 dice is: P(11) = 1/18.For explanation see answer to question: "What is the probability of rolling 7 or 11 with 2 dice?".Read more: What_is_the_probability_of_rolling_7_or_11_with_2_dice
What is the probability of rolling dice with the sum 13?
Assuming 2 dice, it is 0.
When two dice are rolled what is the probability of not getting a sum of 12?
The probability of rolling 12 with 2 dice is 1 in 36. The probability of not rolling 12 with 2 dice is 35 in 36.
What is the probability of rolling a sum of 8 when rolling two dice?
5 in 36
What is the probability of rolling two dice and getting the sum of 1?
Zero. The minimum value of two dice being rolled is two.
What is the probability of rolling a sum of 6 or less with two dice?
The probability is 1, if the dice are rolled often enough.
When rolling two dice what is the probability the sum is greater than 1?
The probability is 1.
What is the probability of rolling two dice and the sum is not divisible by 5?
The probability is 29/36.
What is the probability of rolling a 12 in a single roll of two dice?
The probability of rolling a sum of 12 in a single roll of two dice is 1 in 36, or about 0.0278.
What is the probability of rolling a sum of 8 and doubles when rolling two dice?
The probability of rolling a sum of 8 and doubles when rolling two dice is 1 in 36, or about 0.02778. Simply note that there are 36 permutations of two dice, of which exactly one of them (a 4 and a 4) matches the conditions specified.
