A2011 study by the national safety council estimated that there are nearly 5.7 million traffic accidents year. at least 28% of them involved distracted drivers using cell phones or texting. the data showed that 11% of drivers at any time are using cell phones . car insurance companies base their policy rates on accident data that shows drivers have collisions approximately once every 19 years. that’s a 5.26% chance per year. given what you know about probability, determine if cell phone use while driving and traffic accidents are related.
