Add the function call to the onchange attribute.

onchange="answered(this.value);this.form.submit();"

Edit:

Sorry, misunderstood your question. I though answered was a JavaScript function.

You have POST as your form method, so when it is submited you have to use $_POST to get the data, not $_GET. Try this instead:

answered( $userid, $answerid, $_POST["answer"] );

Try to do this one:

<script>
    function doSmTh(ths)
    {
        /*some actions*/

        document.forms['formName'].submit();
    }
</script>

     <form action="" id="formName" name="formName" method="post">  
        <select name="answer" onchange="doSmTh(this)" >
            <option>Choose Answer</option>
            <option value="1">1</option>
            <option value="2">2</option>
            <option value="3">3</option>
        </select>
     </form>

If you submit the form when the user selects anything, which it looks like you do, you can just handle it like you would any other form being submitted.

If you want to do it without reloading the page you have to use Javascript and AJAX. And if so, you might find some pointers in this sample code: http://samples.geekality.net/tail. This posts some data using jQuery Ajax to a php file which then calls a function and returns some result.
