Final answer:
The question pertains to the law area of study, specifically traffic regulations, where drivers can receive point reductions for having no moving violations, promoting safe driving. The probability aspect relates to a hypothetical study analyzing driving behaviors, such as cell phone usage or clean driving records.
Step-by-step explanation:
The question regarding points being subtracted from a license for having no moving violations relates to traffic laws and regulations, a subcategory within legal studies. In many jurisdictions, drivers are rewarded with point reductions on their driving record for maintaining a clean driving history without any moving violations. This incentive system is designed to encourage safe driving habits by offering tangible benefits to those who obey traffic laws consistently.
When calculating the probability of a certain event such as the number of participants who use a cell phone while driving, have no violation in the past year, or both, it involves a statistical analysis of available data. If such a study were conducted, it would involve looking at the relevant population, identifying those who meet each criterion, and then using probability rules to find the number of participants who meet at least one of the criteria.
