To expand on what thraxil has said...
This probability and permutations exercise could be written as:
#!/usr/bin/perl -w
use strict;
my $DAYS_IN_YEAR = 365;
print "\n# of People \t Birthday Match Likelihood\n" . '-'x80 . "\n";
for my $people ( 2 .. 40 ){
my $tmp_days = $DAYS_IN_YEAR;
my $probability=1;
for ( 1 .. $people ){
$probability *= $tmp_days--;
}
$probability /= $DAYS_IN_YEAR ** $people;
$probability = ( 1 - $probability ) * 100;
print "$people \t\t $probability %\n";
}
exit;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
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).
