If the marbles are drawn with replacement, it means that the starting situation is THE SAME at each trial - 

    the same as it is given/described by the condition.



In particular, it means that in this probability experiment the situation at the second trial is the same as at the first.



Therefore, the answer to the problem's question is


    P =  =  =  = 0.3333 = 33.33%.
