Probability

• 
  Comparison of the probabilities to have a number, between the sum of three dice and the sum of the best three amongst four dice — this is used in some roleplaying games
• 
  Comparison of the probabilities to have a given result (top) or to make less than a given threshold (bottom) with a twenty-sided die (1d20), with the sum of two ten-sided dice (2d10) and of three six-sided dice (3d6)
• 
  Probabilities to get a number (top) or to have less than a given threshold (bottom) by summing several six-sided dice (nd6)
• 
  Probability to exceed a given threshold with the sum of several six-sided dice (nd6). The points linked by a broken lines correspond to a given threshold. The abscissa corresponds to the total number of dice that are thrown.
• 
  Probability to have at least one die with a value equal to or exceeding a given threshold amongst n dice thrown — this is used in some roleplaying games
• 
  Probability to have a value with an "open ended" d20 (the die is thrown again recursively when and added when the result is 20, or subtracted when the result is 1)
• 
  Probability to roll above a given threshold with an "open ended" d20 (the die is thrown again recursively when and added when the result is 20, or subtracted when the result is 1)
• 
  Probability to get a value by summing two chosen dice amongst n
• 
  Probability to get a value by choosing the best amongst two different dice
• 
  Probability to reacha value or make better by choosing the best amongst two different dice
• 
  Same with three dice
