Coding for random answers

I'm working on my first project with FB, I can't figure out how to code for the answers to user given questions to be generated at random,  ie: "The answer is YES / NO / Maybe"

This is what I have so far for that part of it.

<fx:Script>

                    <![CDATA[

                              function displayAnswer()

                              {

                                        var object:Object = new Object();

                                        object.a = " Yes"

                                        object.b = " No"

                                        object.c = " Maybe"

                                                  lblAnswer.text="The Answer is"+object.c  //I can generate the ansewr i want with this but how do i randomize between objects "a-c"

                              }

                    ]]>

</fx:Script>

please let me know if I'm going about this all wrong, I'm using FB 4.6 this is an Air build

Thanks
