Question #3c669

Answer 1

Both:
Green `= 1/25`
Red `= 9/100`
Blue `= 1/4`

Red and blue(the order is irreverent because of the replacement) `= 3/20`

Explanation:

The overall of marbles are 10 which mean that the blue probability is `5/10=1/2`, the red
`3/10`, and the green
`2/10=1/5`.
No matter which draw since they have replacement.
Since you need to check both of them you need to use `xx` (if it was "or" we'll use +)
A. Both red `3/10xx3/10=9/100`

C. Both blue `1/2xx1/2=1/4`
D. Red and blue(the order is irreverent because of the replacement. `3/10xx1/2=3/20`
