Only 10th, 11th, and 12th graders go to East Hamilton. The ratio of 10th graders to the students whole population is 86:255 and the ratio of 11th graders to the total population is 18:51. If 1 student is chosen at random from the entire school, which grade is that student most likely to be in?
What is 11th grade
18:51 = 90:255 = 11th graders
255-90-86 = 12th graders
12th: 79 11th: 90 10th: 86
