Geometric Probability Geometry 10.8 Mr. Belanger P(event)= An event is any outcome that happens when a game/experiment is done. In terms of geometry we are thinking about shapes… Probability of hitting a section on a dart board. Probability of throwing the bean bag through the hole. Probability of getting the ring on the Coke bottle.
