yellow Probability:2/5

black Number of Beads:4

Step-by-step explanation best of luck

Answer 2

Green Probability: 2/5

Yellow Probability: 2/5

Black Number of Beads: 4

If the chance to get a black bead is 1/5 the chance to get green or yellow has to be 4/5. Since both have the same amount of beads, the chance is 2/5 for each of them.

Now we know that 8 beads = 2/5 chance.

To find the number for 1/5 we just divide by 2.

8/2 = 4
