what is the probability that a point chosen inside the large rectangle is not in the shaded region?
18%
36%
42%
64%

The whole area (shaded and un-shaded) is 5*10 units, or 50 units.

The shaded area is 3*6 units, or 18 units.

Subtract 50 - 18 to find the area of the un-shaded region → 32 units.

This means the probability that a point chosen in the large rectangle is un-shaded is 32/50 or 64%

noncoplanar points are points that do not lie on the same line.
