The width of the board is 8 ft.

The height of the board is 10 ft.

The diameter of the circle is 1.5 ft.

The probablity of not circle can be determined as,


\begin{gathered} P(Not\text{ Circle)=1-P(Circle)} \\ =1-((\pi)/(4)d^2)/(w* h) \\ =1-((\pi)/(4)(1.5)^2)/(8*10) \\ =0.9779 \\ =0.9779*100\text{ Percent} \\ =97.79\text{ Percent} \\ =97.8\text{ Percent} \end{gathered}

Thus, the required probablity to the nearest tenth is 97.8%.
