Should the result label still be centered, or aligned to the radio buttons? If centered, you could try this:
<html>
<head>
<script src='https://code.jquery.com/jquery-1.12.4.min.js'></script>
<script type='text/javascript'>
$(document).ready(function()
{$('#btnGetValue').click(function()
{
var selValue = $('input[name=rbnNumber]:checked').val();
$('p').html('<br/>You Selected : ' + selValue + '');});});
</script>
<script>function buttonClickHandler(){}</script>
</head>
<body>
<div style="text-align:center">
<div style="display:inline-block;text-align:left">
