Some worry that playing video games on the phone, computer, TV, and/or tablet for too long can cause vision problems in children and young adults, especially given today's technological age and the COVID-19 pandemic. Assume that a study was done recently on this topic that showed that teenagers who play video games for 550 minutes or more may experience eye strain, dry eyes, and other eye-related conditions. The lengths that teenagers (aged 13-19) play video games per week was found to be normally distributed with a mean of 350 minutes and a standard deviation of 100 minutes. Calculate the probability that a randomly selected teenager plays video games for 550 minutes or more weekly (and is therefore at risk of eye strain).
