Concrete numbers and cases you can check against the tool above.
2d6 and a d20
Two six-sided dice sum from 2–12 with 7 as the most common total. A d20 is uniform 1–20 if the roller is fair. Rolling many dice at once is for damage totals and classroom expected-value demos, not for replacing a missing physical die in a tournament that requires physical dice.
