Question

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
