Presentation transcript:

10-8 Geometric Probability To use segment and area models to find the probability of events. Using a knowledge of length and area, students will compute the probability of a point ending up along a certain length or within a certain area. They will make an initial simplifying assumption about a probability ratio and then compute the ratio accurately to justify their conjecture.
