Answer: 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
