That probability is approx. 40%.  See below.

Step-by-step explanation:

That probability is the area of the purple section divided by the total area of the square before coloring purple.

This area of the square is (12 cm)^2, or 144 cm^2.  

Half the area of the circle is pi*(3 cm)^2, or 9*pi cm^2.

Thus, the purple area is (144 cm^2) / 2  - (9/2)*pi cm^2, or (72 - 9*pi/2) cm^2.  This is approx. 57.86.

The ratio of this purple area to the full area of the square is:

57.86 cm^2

= 0.4 (approximately)
