You rolled 5 - right around the expected average.

  • With 2 D4, the theoretical mean is 5.00 and results range from 2 to 8.
  • Your roll sits roughly 50% of the way from the minimum to the maximum possible.
  • Each face of a fair D4 has a 1-in-4 (25%) chance on any single die. More dice make the distribution bell-shaped and the mean a reliable prediction.
