How to Get Random Numbers from a Set?

Here is what I would like to happen but I’m a newbie to actionscript:

There are three dynamic text boxes. I would like each of them to display a random number but I would like that number to be from a set of 6 options (such as the numbers can only be 1, 5, 10, 25, 50, or 100). How would I do this?

Thank you!
