Drawing a red marble on the first draw
Drawing a blue marble on the second draw
Drawing a red marble on the second draw
Drawing a green marble on the first draw

Since there is replacement after the first draw, drawing a red or blue on the second draw is not dependent on the outcome of the first draw.
