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
B. Both green 1/5xx1/5=1/25
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
