Problem
If a dart is thrown at the 
target, what is the probability that it will hit the shaded area?
![[asy] filldraw((2,2)--(4,6)--(6,6)--(6,4)--cycle,blue); filldraw((2,2)--(6,2)--(6,1)--cycle,blue); filldraw((2,2)--(0,0)--(0,1)--cycle,blue); filldraw((2,2)--(0,4)--(0,6)--cycle,blue); for(int i=0;i<7;++i){ draw((0,i)--(6,i),black); draw((i,0)--(i,6),black); } dot((2,2));dot((0,4));dot((0,6));dot((4,6));dot((6,6)); dot((6,4));dot((6,2));dot((6,1));dot((0,0));dot((0,1)); [/asy]](http://latex.artofproblemsolving.com/d/f/1/df1c252b085c82d7d67511a0e58cc24d9595ae8a.png)
Solution
To solve this we start by breaking it up into it's four shaded areas. Starting with the bottom right one, it splits four squares and hits the vertex on the last one, so we know that the total area of that region in two squares.
