How to add random fact onto scene

Question

I'm currently making a game to educate children. The game is a recycling game and when they collect more then 5 items a random fact will appear.
so far these are the facts I have used...
var b = new Array()
b.push ("Glass can be recycled virtually forever. It never wears out.")
b.push ("Most bottles and jars that you use contain at least 25% recycled material.")
b.push ("The energy saved by recycled just one bottle could light a 100-watt bulb for 4 hours.")
b.push ("Paper made from recycled paper uses 70% less energy.")
b.push ("98 tons of various resources are required to make one ton of paper.")
b.push ("75% of each tree that is cut down for paper is not used in a paper product.")
b.push ("We get through nearly 3 billion disposable nappies each year in the UK alone and around 90% of these end up on landfill sites. Disposable nappies take 500 years to decompose.")
b.push ("Every tonne of paper recycled saves 17 trees.")
Now I was hoping to find out how I can make them show up randomly 1 at a time.
Thanks for any help

Answer 1

make a dynamic text field (and name the instance (in this case I named it textField))
Make a timer event:
var textTimer:Timer=new Timer(1000)
textTimer.addEventListener(TimerEvent.TIMER,textChange)
textTimer.start()
Then make the function to change the text:
function textChange(e:TimerEvent):void
     var textNumber:Number = Math.floor(Math.random()*b.length)
     textField.text = b[textNumber]
