Once
![\sqrt{xy} = 6](https://tex.z-dn.net/?f=%5Csqrt%7Bxy%7D%20%3D%206)
We know that ![xy = 36](https://tex.z-dn.net/?f=xy%20%3D%2036)
There are infinity values for
, but considering ![x, y \in \mathbb{Z}](https://tex.z-dn.net/?f=x%2C%20y%20%5Cin%20%5Cmathbb%7BZ%7D)
Below we have all the solutions for ![x, y](https://tex.z-dn.net/?f=x%2C%20y)
Negative:

Positives:
![x = 36 \text{ and } y = 1\\x = 18 \text{ and } y = 2\\x = 12 \text{ and } y = 3\\x = 9 \text{ and } y = 4\\x = 6 \text{ and } y = 6\\x = 4 \text{ and } y = 9\\x = 3 \text{ and } y = 12\\x = 2 \text{ and } y = 18\\x = 1 \text{ and } y = 36\\](https://tex.z-dn.net/?f=x%20%3D%2036%20%5Ctext%7B%20and%20%7D%20y%20%3D%201%5C%5Cx%20%3D%2018%20%5Ctext%7B%20and%20%7D%20y%20%3D%202%5C%5Cx%20%3D%2012%20%5Ctext%7B%20and%20%7D%20%20y%20%3D%203%5C%5Cx%20%3D%209%20%5Ctext%7B%20and%20%7D%20%20y%20%3D%204%5C%5Cx%20%3D%206%20%5Ctext%7B%20and%20%7D%20%20y%20%3D%206%5C%5Cx%20%3D%204%20%5Ctext%7B%20and%20%7D%20%20y%20%3D%209%5C%5Cx%20%3D%203%20%5Ctext%7B%20and%20%7D%20%20y%20%3D%2012%5C%5Cx%20%3D%202%20%5Ctext%7B%20and%20%7D%20%20y%20%3D%2018%5C%5Cx%20%3D%201%20%5Ctext%7B%20and%20%7D%20%20y%20%3D%2036%5C%5C)
We can see that ![x + y \neq 18](https://tex.z-dn.net/?f=x%20%2B%20y%20%5Cneq%2018)
Think of the contents of the bag having 6 equal parts (in numerical quantity). Then the fraction of all the marbles which happen to be white marbles is 1/6. This converts to 16.67%.
The answer is 2/5.
There is an 8/20 chance that the next person will receive a window seat. You simplify that probability to get your answer. 8/20 becomes 2/5. So the answer is 2/5.
