Quizplus · Accepted Answer

The sum of 3 can only be achieved by rolling a 1 on one die and a 2 on the other. Since there are 36 possible outcomes when rolling two dice (6 options for the first die multiplied by 6 options for the second die), and only 2 of these outcomes (1+2 and 2+1) sum to 3, the probability is $\frac{2}{36} = \frac{1}{18}$.
