We can use geometric models to solve certain types of probability problems. In geometric probability, points on a segment or in a region of a plane represent outcomes. The geometric probability of an event is a ratio that involves geometric measures such as length or area. Consider the given diagram.
We will find the area of the entire figure and the area of the shaded region one at a time. Then, we will find their ratio.
The figure is square of side length 5 meters. We can find its area by using the formula for the area of a square. Area of the Figure: 5^2=25m^2
The area of the shaded region is the difference between the area of the figure and the area of a square with side length 3 meters. We already know that the area of the figure is 25 square meters. Let's calculate the are of the inner square. Area of the Inner Square: 3^2= 9m^2 To find the area of the shaded region, we will subtract the area of the inner square from the area of the entire figure. Shaded Area: 25 - 9= 16 m^2
