Do you have any idea how to start?

You need to calculate the area of the circles and the area of the square. As an example you could insert 1 and 2: Take a look at the picture

anonymous · Answer

let us assume the size of the side of a square be a . Now can you calculate the area of square?
also can you calculate the area of circle in terms of a?

anonymous · Answer

a circle is a=pier^2

anonymous · Answer

probability of shaded region = 4*area of circle/total area of square
can you solve from here?

anonymous · Answer

$$A_{circle}=\pi*r^2$$
$$A_{square}=a*b$$
