Crazy dice is a mathematical exercise in elementary combinatorics, involving a re-labeling of the faces of a pair of six-sided dice to reproduce the same frequency of sums as the standard labeling. The Sicherman dice are crazy dice that are re-labeled with only positive integers .
Diceware is a method for creating passphrases, passwords, and other cryptographic variables using ordinary dice as a hardware random number generator. For each word in the passphrase, five rolls of a six-sided die are required. The numbers from 1 to 6 that come up in the rolls are assembled as a five-digit number, e.g. 43146. That number is ...
Dice pool systems generally use a single size of die, the most common being six-or ten-sided dice (d6s or d10s), though in some games a character's Attributes or Skills may determine the size of the dice in the pool, as well as their number (such as Deadlands). While such games may require different sized dice for different rolls, the dice in a ...
7th Sea and Legend of the Five Rings use only 10-sided dice, so it omits the number of sides, using notation of the form , meaning "roll eight ten-sided dice, keep the highest six, and sum them."Although using a roll and keep system, Cortex Plus games all use roll all the dice of different sizes and keep two (normally the two best), although a ...
In analogy to the intransitive six-sided dice, there are also dodecahedra which serve as intransitive twelve-sided dice. The points on each of the dice result in the sum of 114. There are no repetitive numbers on each of the dodecahedra. Miwin's dodecahedra (set 1) win cyclically against each other in a ratio of 35:34.
Comparison of probability density functions for the sum of n dice to illustrate the central limit theorem: Image title: Comparison of probability density functions, p(k) for the sum of n fair 6-sided dice to show their convergence to a normal distribution with increasing n, in accordance to the central limit theorem; illustrated by CMG Lee.
[6] A quincuncial map is a conformal map projection that maps the poles of the sphere to the centre and four corners of a square, thus forming a quincunx. The points on each face of a unit cell of a face-centred cubic lattice form a quincunx. The quincunx as a tattoo is known as the five dots tattoo.
So the player has a 41.8% chance of throwing a 1 and a 4 on the first throw of the dice and a 74.2% chance of throwing a 1 and a 4 after the second throw of the dice. The formula can be used to calculate the maximum probability of scoring when the player has less than 6 dice.
