The DuPage County Public Health Department wishes to assess the rate of tobacco use and vaping among local high school students. There are 52,422 high school students registered in DuPage County; 23,134 students are ages 14-15 and 29,288 students are ages 16-18 years old. The County randomly selects 3,000 students that are 14-15 years old and 5,000 students that are 16-18 years old. If a child is 17 years old, what is the probability they will be selected to participate in the study
