The average outcome of rolling a standard die equals what?

Explanation:
When a fair die is rolled, each face from 1 to 6 has the same chance, so the average outcome is the expected value, or the mean, of all possible results. Add them up: 1+2+3+4+5+6 = 21. Divide by the number of outcomes (6) to get 21/6 = 3.5. You can also see this by pairing outcomes that sum to 7; each pair averages to 3.5, so the overall average is 3.5. Therefore, the average outcome is 3.5.
