Dice Play

This site explains Dice Notation, the way dice are spoken of in RPGs for example: 3d6, 1d20, 27d43.
3d6 is notation for three: six sided dice, 1d20 is one: 20 sided die and 27d43 (not actually possible with traditional dice) is 27: 43 sided dice.

I chose this because Dice notation is actually part of the probability in dice and determines the probability to reaching a certain outcome for example 1d6 meaning one: six sided die, has a flat probability as all numbers have the same probability of being rolled, however, 3d6 meaning three: six sided dice have a bell curve of reaching certain results thus making the extremes less probable than a number closer to the middle result (10.5).
