Final answer:
On average, eight teens are killed each day in motor vehicle crashes in the US, making it unlikely for there to be more than 20 deaths or no deaths on a given day.
Step-by-step explanation:
On average, there are eight teens in the United States who die every day from motor vehicle injuries. It is not likely that more than 20 teens would be killed from motor vehicle injuries on any given day, as this number significantly exceeds the daily average. If we were to see 20 or more teen deaths in a day due to motor vehicle crashes, it would represent a substantial and atypical increase from the established average.
Regarding the probability of having no teen fatalities on a given day, while statistically possible, it is highly unlikely given the average daily rate. Moreover, examining the changes over time and statistical data, such as the numbers provided by US Census Bureau or findings by American Automobile Association (AAA), indicates that motor vehicle crashes remain a critical issue in terms of public health and safety.
