# RE: VMs: magical voynich dice game ... "gaussianity"

```The (shifted) distribution of values generated by two dice is not at
all similar to a Gaussian. It is a triangular graph, 6 - abs(x - 6),
for x from 1 to 11. That's because one can get the sum```

Hi,
The graph of a 2 dice roll looks "not so gaussian" beacause it is produced by only 2 dice ... if you use 4 dice its "gaussianity" is revealed:
Of course only if you have tons of dice (infinite) you'll get a perfect gaussian curve.
Google --> "gaussian curve"

However taking out numbers 5, 9, 11 (or equivalently 5, 9, 3) from a sequence of 2 dice rolls you obtain the same distribution frequencies of the word lengths in VM.
