Answer: \dfrac{15}{64}

Step-by-step explanation:

Given

Inside radius of figure r_1=\frac{14}{2}=7\ ft

Outside radius of figure r_2=\frac{16}{2}=8\ ft

Area of outside region is A_1=\pi (8^2)

Area of inside region A_2=\pi (7)^2

Area of shaded region A_1-A_2

Probability that point lies inside the shaded region is

\Rightarrow P=\dfrac{A_1-A_2}{A_1}\\\\\Rightarrow P=\dfrac{\pi (8^2-7^2)}{\pi 8^2}\\\\\Rightarrow P=\dfrac{64-49}{64}\\\\\Rightarrow P=\dfrac{15}{64}
