The police department is keeping track of distracted drivers and accidents. They have found that if a driver is distracted, the driver has a 30% chance of being in an accident. If the driver is not distracted, the driver has a 2% chance of being in an accident. The probability of a driver being distracted is 10%. If needed, create a tree diagram on a separate piece of paper. Then use the diagram to answer the questions. a. What is the probability a driver will be in an accident? Explain. b. What is the probability that a driver who was in an accident was distracted? Explain.

Draw out a tree to get this |dw:1364249812316:dw|

8. jim_thompson5910

Now find the probability of each branch so for instance the first uppermost branch would be 0.1*0.3 = 0.03 |dw:1364249966115:dw|

9. jim_thompson5910

To find the probability of being in an accident, add up the accident probabilities to get 0.03+0.018 = 0.048

What is the probability that a driver who was in an accident was distracted? P(Distracted|Accident) = P(Distracted and Accident)/P(Accident) P(Distracted|Accident) = ???
