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?
+1008
