Something to be aware of. I realized you can't use rand in an equation with other rand's since the calculation affects the other call to it.
Here is an example:
A simulation of 3 six sided die rolls added together for 50 trials.
for i from 1 to 50 do
You'll notice the rand calls have affected the other calls to rand, and has eliminated some possible results.

The idea was to generate values from 1 to 20 (I just chose 20 as an example) using 6 sided dice, and one that which produces as uniform a distrubution as possible. I appreciate the explanations. I chose 4 as the smallest number of rolls needed. In the physical world as n approaches large numbers rolling that many becomes increasingly more difficult and time consuming.
So just wondering what the best solution would be for a uniform distribution in a range from 1 to n using only six sided dice?
