If a bag contains 2 green marbles, 3 3 blue marbles, and 4 red marbles. what is the probability of pulling out a greenmarble then another green marble without replacing the it
If you mean three blue marbles, then 1 in 36. If you mean 33 blue marbles then 1 in 741.
If this is homework then be sure to show your work.

Since there are 3 blue marbles and 7 non-blue marbles for a total of 10 marbles, the probability of choosing a non-blue marble is 7 out of 10.
The probability of choosing another non-blue marble depends on whether you put the first marble back or not.
The steps for solving a probability problem depends on the problem. It's like asking "What are the steps in getting to grandmother's house?" You might be able to get in your car, drive for an hour, and get there. Or you might take a bus or train. In my case, I'd have to go to an airport and board a flight (or else get to a port and board a ship). There's no way I can get there by road.
