Mothers Against Drunk Driving (MADD) is a very visible group whose main focus is to educate the public about the harm caused by drunk drivers. A study was recently done that emphasized the problem we all face with drinking and driving. Five hundred accidents that occurred on a Saturday night were analyzed. Two items noted were the number of vehicles involved and whether alcohol played a role in the accident. The numbers are shown below: Number of Vehicles Involved Did alcohol play a role? 1 2 3 Yes 60 110 30 200 No 40 215 45 300 100 325 75 What proportion of accidents involved more than one vehicle?

4/5

Step-by-step explanation:

No of vehicles involved

Did alcohol play a role - - 1 - - - - - 2 - - - - - 3

Yes 60 - - - - 110 - - - 30=200

No - - - - - - - - - - - - - - - - 40 - -- - 215 - - - 45 =300

- - - - - - - - - - - - - - - - - - 100 - - - - 325 - - - 75

What proportion of accidents involved more than one vehicle;

Total accident = (100 + 325 + 75) = 500

Number of accidents involving more than one vehicle = (accident involving 2 vehicles + accident involving 3 vehicles)

(325 + 75) = 400

Therefore, proportion of accidents involved more than one vehicle = (Accident involving more than one vehicle / total accidents)

= (400/ 500) = 4/5
