Answer:

The correct option is B: 94.1%

Step-by-step explanation:

There are 52 weeks in a year so, if we divide 234 by 12 it gives 4.5 accidents per week on average. Given this information, we can say that in any randomly selected week, there will be an 80% probability of at least two accidents occurring on the said intersection. Hence, this means that a traffic light should be very likely will have to get installed in order to ensure safety of the residents.
