The Probability Scale
(1) Bryn has 5 white beads in a bag. He wants to make it more likely that he will take a black bead than a white bead out of the bag. How many black beads should Bryn put into the bag?

(2) There are 20 beads altogether in another bag. All the beads are either black or white. It is equally likely that Bryn will take a black bead or a white bead from the bag. How many black beads and how many white beads are there in the bag?
