Just thought I'd plug a few Perl6 ways of doing it, for future reference.
my %hash = (
word => 1,
second => 3,
third => 7
);
######
my @weighted = ();
for %hash.keys -> $key {
push @weighted, ( $key ) xx %hash{ $key };
}
say @weighted.pick;
###### Basically the same thing:
my @weighted = ();
push @weighted, ( $_ ) xx %hash{ $_ } for %hash.keys;
say @weighted.pick;
###### One-liner style. *Somewhat* based on Roger's above.
%hash
.keys
.map:{
( $_ ) xx %hash{ $_ }
}
.pick
.say;
## (or actually on one line)
%hash.keys.map:{ ( $_ ) xx %hash{ $_ } }.pick.say;
(And if one of those Perl6 experts comes along, tell him or her that I'm still kinda new to p6, so there might even be better ways to do it! ;)

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 How to display code and escape characters
are good places to start.
