Question

A bag contains 4 red, 2 blue, 6 green, and 8 white marbels. Round anwsers to the nearest tenth. What is the probibility of selecting a green marble, replacing it, and then selecting a red marble.

Answer 1

`(3)/(50)` chance.

Explanation:

Probability of getting a green:
`(6)/(4+2+6+8)` =
`(6)/(20) = (3)/(10)`

Probability of getting red:
`(4)/(4+2+6+8) = (4)/(20) = (1)/(5)`

`(1)/(5) * (3)/(10) = (3)/(50)`

There is a
`(3)/(50)` chance of getting a green then red marble with replacement.
