A box contains 55 green marbles and 1515 white marbles. If the first marble chosen was a green marble, what is the probability of choosing, without replacement, another green marble? Express your answer as a fraction or a decimal number rounded to four decimal places.
Depends on the beginning of the question. if the first one was NOT replaced your answer is 54/1570 BUT if the first one WAS replaced then the answer is 55/1570.
