Quizplus · Accepted Answer

The sum of the two numbers on the dice will be 3 only in two cases: (1,2) and (2,1). Since there are a total of 36 possible outcomes when rolling two 6-sided dice (6 outcomes for the first die multiplied by 6 outcomes for the second die), the probability is $\frac{2}{36} = \frac{1}{18}$.
