Question 316472: A target consists of concentric circles of radii 1 cm, 2 cm and 3 cm. The innermost circle is colored red, the middle ring is colored white, and the outer ring is colored blue. If a point is chosen at random on the target, what is the probability that it lies in the blue region? Express your answer as a common fraction.

Calculate the areas of each region.
The total target area is,

The probabilities for each color is determined by the amount of area in each region compared to the total area.

So, the probability of a blue region pick is 5/9.
