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 are told that a point on AK is chosen at random, and want to find the probability that the point lies on GK.
The probability that the point is on GK is the ratio of the length of GK to the length of AK.
P(The point is onGK)=GK/AK
Looking at the given number line, we can see that AK= 10 and GK= 4.
We can substitute these values in the above formula to find the probability that the point lies on GK.
