Geometric probability is a branch of mathematics which deals with the probability of certain geometrical shapes forming or intersecting. In geometric probability, a variety of shapes are studied, such as circles, triangles, and lines. These shapes are then used to calculate the probability of certain events taking place. For example, one can calculate the probability of two circles intersecting, or the probability of a line segment hitting a circle. Geometric probability can be used to calculate the probability of many real-world events, such as the probability of a certain object being hit by a thrown ball. With the help of geometric probability, it is possible to calculate the likelihood of various events in the physical world.
