Even; is straight or has the same shape as another
Odd; is being off or odd about the shape it is on or is next to
On a graph even will look like its ex;a horizontal line and next to it will also have a horizontal line.
For odd ex; a vertical and next to it a horizontal line different.
We must find UNIQUE combinations because choosing a,b,c,d... is the same as d,c,b,a...etc. For this type of problem you use the "n choose k" formula...
n!/(k!(n-k)!), n=total number of choices available, k=number of choices made..
In this case:
20!/(10!(20-10)!)
20!/(10!*10!)

The location of the fountain as described in the task content is; (-1, -0.5).
<h3>What is the location of the Fountain?</h3>
According to the task content, the locations of Fernando and Maria are given as; (-4, -2) and (4,2) respectively and the ratio of division is expected to be; 5: 3.
Hence, the coordinates of the fountain can be evaluated as;
x = (4) - (4-(-4)) × (5/8) = -1.
y = 2 - (2-(-2)) × (5/8) = -0.5
Hence, it follows that the coordinates of the fountain location is; (-1, -0.5) since the fountain is closer to Fernando than Maria.
