Question

Quizplus · Accepted Answer

The possible positive differences when rolling two fair 6-sided dice range from 0 (when both dice show the same number) to 5 (when one die shows 6 and the other shows 1, or vice versa). These differences are not equally likely because there are more ways to roll a smaller difference (e.g., there are 6 ways to roll a difference of 0, but only 1 way to roll a difference of 5).
