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;

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
