 Need Help??
I had a program similar that gave averages and standard deviations.

However, if you are just trying to get a feel for things then perhaps a graph would be better. So I whipped this up for you relatively quickly.

It will either do a statistical sample, like yours, or do an exaustive population count (give it 0 for the samplesize).

Enjoy:

```#!/usr/bin/perl -w
use strict;
my \$dicemax = shift @ARGV || 6;
my \$numdice = shift @ARGV || 6;
my \$dicekeep = shift @ARGV || 6;
my \$samplesize = shift @ARGV || 0;

my \$totstates = \$dicemax ** \$numdice;
my \$min = \$dicekeep;
my \$max = \$dicekeep * \$dicemax;
my \$num = \$max - \$min + 1;

my @tot; @tot[\$min..\$max] = map {0} (\$min..\$max);

if (\$samplesize) {
srand;
for my \$x (1..\$samplesize) {
my \$sum=0;
\$sum += \$_ for (sort {\$b<=>\$a}
map {int rand(\$dicemax)+1} (1..\$numdice)
)[0..\$dicekeep-1];
\$tot[\$sum]++;
}
\$totstates = \$samplesize;
} else {
my \$count = 0;
my @dice = map {1} (1..\$numdice);
while (\$count++ < \$totstates) {
my \$x = 0;
\$dice[\$x]++;
while (\$dice[\$x] > \$dicemax) {
\$dice[\$x++] = 1;
\$dice[\$x]++;
}
my \$sum=0;
\$sum += \$_ for (sort {\$b<=>\$a} @dice)[0..\$dicekeep-1];
\$tot[\$sum]++;
}
}

my @per; @per[\$min..\$max] = map {\$_/\$totstates*100} @tot[\$min..\$max];

my \$maxper = (sort {\$b<=>\$a} @per[\$min..\$max])[0];

print "Roll Percent| Frequency Graph (0 - \$maxper%)\n";
for my \$x (\$min..\$max) {
my \$c = (\$num-\$x+\$min)/\$num*\$maxper;
printf "%3d   %5.2f | ", \$x, \$per[\$x];
do { print \$per[\$_] > \$c ? "*" : " " for (\$min..\$max) }
if \$max-\$min < 75;
print "\n";
}
print "-"x(16+\$max-\$min),"\n";
for my \$x (100,10,1) {
print " "x14,map {int \$_ / \$x % 10} (\$min..\$max);
print "\n";
}

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
