Question

Solve.

A bag contains 2 red, 4 blue, and 4 yellow marbles. What is the probability of pulling a red marble, then a blue marble from the bag? (to the nearest tenth)

8.1
8.6
8.9

Answer 1

8.9%

Explanation:

Probability of picking a red marble first:
`(2)/(10)=(1)/(5)`

Probability of picking a blue marble (no replacement):
`(4)/(9)`

`(4)/(9) *(1)/(5) =(4)/(45) = 8.8888888888...%` % ≈ 8.9%
