Answer:  

The correct option is D. 9/38x9/38 =81/1444

Step-by-step explanation:

Total number of marbles in the bag = 38

Number of white marbles in the bag = 14

Number of gray marbles in the bag = 9

Number of blue marbles in the bag = 15

We need to find the probability that Jane takes out a gray marble in both draws

\text{Probability that Jane draws gray marble in first draw = }\frac{9}{38}

Given that : Then Jane replaces the marble for the second draw

\text{Probability that Jane draws gray marble in second draw = }\frac{9}{38}

\text{Probability that Jane draws gray marble in both draws = }\frac{9}{38}\times \frac{9}{38}

\text{Probability that Jane draws gray marble in both draws = }\frac{81}{1444}

Therefore, The correct option is D. 9/38x9/38 =81/1444
