A bag contains these beads: 4 white, 6 red, 5 yellow, 5 blue. One bead is selected, KEPT, and another bead is selected. Find P(blue, then blue)

And what's the question?

Srry i have it now

There are 5 blue marbles out of 20, so 1/4.Then we have one reduced bead so (5-1)/(20-1) = 4/19

Multiply these probabilities and you'll have your answer!

Ask if you don't understand anything. :)

So its 4/76?

Yes. Anything you need me to explain?
