Probability theory and stochastic processes Concept

Geometric probability

Builds on Probability space

Summary

Geometric probability studies random geometric objects, such as random points, lines or shapes in the plane or in space. In the simplest case, a point is chosen uniformly in a region Ω\Omega of finite positive area. Then the probability of a subregion AA is the area of AA divided by the area of Ω\Omega. Classic problems are Buffon's needle problem and the Bertrand paradox.

Remarks

The same rule works with length on a line and with volume in space. Mathematicians studied such problems from the 17th century on. Their modern form is part of integral geometry and stochastic geometry.
