Answer:

3/25

Explanation:

3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles

P(green) = number of green / total = 4/10 = 2/5

We replace it

3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles

P(red) = number of red / total = 3/10

P(green, replace,red) =2/5*3/10 = 3/25
