Probability of rolling exactly 7: 16.67%

  • With two D6 dice there are 36 equally likely outcomes. 6 of them give a sum of exactly 7.
  • The average (expected) sum is 7.0, the center of the symmetric distribution.
  • A sum of 7 is the most probable single outcome on two D6 dice - it can be made 6 different ways.
  • On average you would expect to roll exactly 7 about once every 6 rolls.

Next stepUse the "Probability type" selector to switch between exact, at-least, and at-most queries, or change the die type to explore D4 through D20.
