Ok the answer is (1/40)
U find the total number of marbles, and then find the ratio of green marbles to the total number of marbles
Then subtract one from the total number of marbles, u cant replace the green marble, and find the ratio of white marbles to the rest of the marbles
Once u have both rations, just multiply both together and u get a probability of once every 40 times.
Ohh, dont forget to simplify

Didn't you see how to get the answer from the last time you asked this all of ten minutes ago? Look at the answer from the last time you asked and use the same technique.
