Final answer:
The probability of getting a cavity is dependent on whether a 16-year-old drinks 2 or more cans of soda per day due to the high sugar content in sodas that increases the risk of dental caries.
Step-by-step explanation:
The probability of getting a cavity is likely dependent on whether a 16-year-old person drinks 2 or more cans of soda per day. Excessive consumption of beverages with added sugars, such as soda, increases the risk of dental caries (cavities). Therefore, the consumption of sugary sodas may directly impact the occurrence of cavities, suggesting a dependent relationship.
Scientific research has established a link between sugary drink consumption and various health issues, including dental caries. These drinks, which include sugary sodas, have been proven to increase the risk of dental caries as they facilitate bacterial growth and acid production in the mouth, leading to enamel erosion.
Furthermore, reducing sugar intake, maintaining regular dental hygiene, and availing of fluoride treatments are methods that can help prevent cavities. Hence, by increasing the risk of tooth decay through high sugar levels, soda consumption is a factor that affects the likelihood of dental caries, thus exemplifying a dependent probability scenario.
