A teacher models geometric probability with a unit square. Which representation best preserves the sample space?
A
Shade only the boundary line of the event and compare its length to the side length.
B
Use a square with unequal axis scales and estimate probability by visual width.
C
Use the entire unit square as equally likely ordered pairs and shade the region satisfying the event; probability is shaded area divided by total area.
D
Count grid intersection points only because probability should be discrete.
