[jQuery] jQuery Newbie - Getting value of a Select Option


I'm a complete newbie to jQuery trying to perform a relatively simple
task, but can't figure it out.
Based of the value of a select option, I want to hide/show a div. How
do I get the value of the select option? Here's what I have below.
Thanks for your help!
$(document).ready(function(){
    var hearOther = $("#hear_other");
    hearOther.hide();
    $("#hear").change(function(){
        if( $("#hear_other option[value='O']")){
            alert('show hearOther');
        }else{
            alert('hide hearOther');
        }
    });
});
<select id="hear">
    <option value="T">Television</option>
    <option value="R">Radio</option>
    <option value="O">Other</option>
</select>
<div id="hear_other">Please describe &ldquo;Other&rdquo;</div>
