40 balls in bag: 15 red, 25 black. 15 drawn at random.

You have a bag with 40 balls in it. 15 of those balls are red and 25 are black. You select 15 balls at random. What are the odds of all of them being red balls?

We also need know whether this was "with" or "without" replacement. Do you know what those mean?
