RE: VMs: magical voynich dice game ... "gaussianity"
At 04.07 11/09/04, you wrote:
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
02 03 04 05 06 07 08 09 10 11 12 in
1 2 3 4 5 6 5 4 3 2 1 possible ways.

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.
