This should do it...


<html>
<head>
<script type="text/javascript">
function randomChoose(element) {
var randomChoice = (Math.floor((element.length+2-2)*Math.random()) + 3) - 3;
element[randomChoice].checked = true;
}
</script>
</head>
<body>
<form name="theForm">
<input type="radio" name="choice" value="a" /> A<br/>
<input type="radio" name="choice" value="b" /> B<br/>
<input type="radio" name="choice" value="c" /> C<br/>
<input type="radio" name="choice" value="d" /> D<br/>
<input type="button" value="Random Choose" onclick="randomChoose(this.form.choice)" />
</form>
</body>
</html>


You can increase and decrease the number of choices and it should still work.
