Re: TIB: "Weighting" Dice on TI-85
Will this formula do any good? The probability of the number occuring
increases as the number does. In effect
p(1)<p(2)<p(3).... etc.
rand -> x
int(6 * x + ln(x + 1) + 1) -> roll
Simply put, the 6 specifies the number of sides, the rand is stored so I
can have the same random number entered twice in the function.
Comparing the function with the related formula
int(6 * x) + 1
will indicate that the function increases faster, but not enough to
overtake 7. Keep in mind that this will not work out so well in every
case, but it could be corrected by multiplying or dividing the
"weighted" portion of the function ln(x+1).
Let me know if this suits your needs.
