7.8 Geometric Probability Goal: To use segment and area models to find the probabilities of events

You may recall that the probability of an event is the ratio of the number of favorable outcomes to the number of possible outcomes. P(event) = favorable outcomes possible outcomes

Finding Probability Using Segments Sometimes you can use a geometric probability model in which you let points represent outcomes. Finding Probability Using Segments P(event) = length of favorable segment outcomes length of entire segment

Finding Probability Using Area If the points of a region represent equally-likely outcomes, then you can find probabilities by comparing areas. Finding Probability Using Area P(event) = area of favorable region area of entire region
