Jane has 38 marbles of the same shape and size in a box. The colors and amounts of the marbles are shown below: 14 white marbles 9 gray marbles 15 blue marbles Without looking in the box, Jane takes out a marble at random. She then replaces the marble and takes out another marble from the box. What is the probability that Jane takes out a gray marble in both draws? 9 /38 x 8 / 37 = 72 / 1406 9 / 38 + 8 /37 = 637 / 1406 9 / 38 + 9 / 38 = 684 / 1444 9 / 38 x 9 / 38 = 81 / 1444
