Notice that after drawing a marble from the jar, it is dropped back into it; therefore, the probability of picking a marble from any color remains constant.
Therefore, the probability of drawing a green marble at any time is
[tex]P(green)=\frac{5}{9+5}=\frac{5}{14}=[/tex]
Notice that the events of drawing a marble, putting it back in the jar, and drawing a second time are independent.
Thus, the answer is 5/14
