I believe this is a rotation through an angle of +90°, anticlockwise, (counterclockwise), with the center of rotation origin(0,0)
To describe rotation we give the center of rotation and the rotation angle in degrees stating whether it is clockwise or counterclockwise.
I believe the percentage of this is 50%. Half the numbers are even, and half are odd. Your fraction is

Simplified, that's a 50% probability.
