Geometry Probability

A square dart board is shown below. The shaded portion in the center is a square whose side is 15 inches. A dart thrown at the board is equally likely to land on any point on the dart board. What is the probability that a dart will land on the shaded area? Write your answer as a fraction in simplest form.
