The probability is 1, if the dice are rolled often enough.

1/6 because the other numbers don't affect the probability

The first dice can show any of the eight numbers. If the dice are to show different numbers the second dice has 7 different numbers out of a possible 8 to chose from. So the probability is 7/8 or 0.875 or 87.5% chance.

Prob(Sum = 5) = 1/9
