How do I put an answer in a randon position in a math game?

Question

I have a math game I'm working on and I would like to have the answers appear in random positions. For example:
3 x 11 = ?
9    0    33
The answer is obviously 33, position 3. Right now the answer will appear in position 3 every time.
In the next problem I don't want the answer to appear in the same position. I want it to appear in another position randomly. So for example the next problem will have the answer in position 1:
3 x 4 = ?
12    14     73
I am currently putting the answers in a dynamic text box that is already on the stage. I thought about using an array but I can't figure that part out.

Answer 1

if you have 3 textfields (eg, tf1,tf2,tf3) for the answers, you could use:
var answersA:Array=[[x11,x12,x13],...,[9,0,33],...,[xn1,xn2,xn3]];
where the 3 answer choices for question 1 is x11,x12,x13 and the 3 answer choices for the nth question is xn1,xn2,xn3
you could use:
function displayAnswersF(i:int):void{
// display answers for the ith question
var answerA:Array = answersA[i];
answerA.shuffle();
tf1.text=answerA[0].toString();
tf2.text=answerA[1].toString();
tf3.text=answerA[2].toString();
function shuffle(a:Array) {
    var p:int;
    var t:*;
    var ivar:int;
    for (ivar = a.length-1; ivar>=0; ivar--) {
        p=Math.floor((ivar+1)*Math.random());
        t = a[ivar];
        a[ivar] = a[p];
        a[p] = t;
