No area is covered by those coordinates. (0,0) (2,0) and (4,0) make up a line.

It is the origin itself 0,0 as it is X Axis

(0,0), (2,0) and (4,0) are 3 points on a line segment having boundaries as (0,0) and (4,0). This line segment is on the x-axis.
In this entire line segment, the only point where x=y will be at (0,0).
Hence, number of results = 1.
However, the total number of points possible on this line segment = infinite.
Hence, the probability should be 1/infinite.

Doesn't matter if 3 points are on the line or not.
Anyway the answer will be P = (N)/(infinity),
where N=relatively small number
so P = 0

i think he made a typo. it probably should be (0,4) to form a triangle.

If so, the probably will be the length of the line segment to the area of the triangle. It is root(2)/3, roughly about 1.142/3.
