Exercise 6 Page 772

When calculating experimental probability, we are comparing the number of times an event occurs to the number of times the experiment is done. P=Times the Event Occurs/Times the Experiment Is Done This is very similar to the Probability Formula. We are told that the bull's-eye is hit 80 times, which is the number of times the event occurs. We also know that the dart is tossed 500 times, which is the number of times the experiment is done. Now we have enough information to calculate P(hit).

P=Times the Event Occurs/Times the Experiment Is Done
