Quizplus · Accepted Answer

To find the proportion of accidents involving a single vehicle given alcohol was involved, we need to look at the total number of alcohol-involved accidents that had only one vehicle (50) and divide it by the total number of alcohol-involved accidents (170). This gives us 50/170 or 29.41%. To find the proportion of accidents involving a single vehicle when alcohol was involved, we need to look at the table given in the scenario. Out of the 170 accidents involving alcohol, 50 involved a single vehicle. Therefore, the proportion of accidents involving a single vehicle when alcohol was involved is 50/170 or 29.41%.
