There is a 16.67% chance of rolling exactly the target sum with 2d6.

  • The expected (average) total when rolling 2d6 is 7.0.
  • You need roughly 4 rolls to have a 50% or better chance of seeing this outcome at least once.
  • Each roll of the dice is an independent event, so past results do not influence future rolls.

Next stepTry the "sum at least" or "sum at most" modes to see the cumulative chances for ranges of outcomes.
