To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area
Let
x ----> the area of the hole
y ----> the area of the playing game
so

we have

<em>Find the area of the hole</em>
The area of the circle (hole) is equal to

we have
----> the radius is half the diameter
assume

substitute


<em>Find the probability</em>

we have
