What throws me off is how it is set up, for example, looking at Driver on the left then Seeing Pedestrian in the middle. It says Intoxicated, I am not exactly sure which one to really count and which one to count as intoxicated and which one not. Sorry if that sounds confusing.
Sorry if that sounded confusing.
The question asks for the cases where either the pedestrian was intoxicated (but not the driver) or the driver was intoxicated (but not the pedestrian) or when they were both intoxicated. Of course, the question didn't use all of those words. It just stated OR which means that it is the union of these two events (ie: those 3 cases I wrote out).
The 226 entry represents the number of pedestrians that were killed while the driver was not intoxicated but the pedestrian was intoxicated - so this entry is part of the union. Similar with the entry 97 entry except it is the driver that was intoxicated and the pedestrian was not.
