Determine the area of square with side a = 8 cm.


\begin{gathered} A=(a)^2 \\ =(8)^2 \\ =64 \end{gathered}

Determine the area of NOT shaded region.


\begin{gathered} A^(\prime)=2\cdot(1)/(2)\cdot4\cdot4 \\ =16 \end{gathered}

Determine the probability for the point in square NOT lie in shaded region.


\begin{gathered} P=(16)/(64) \\ =(1)/(4) \end{gathered}

So answer is 1/4.
