Mindscapes Lesson 9.5 #17

College town - you go to school in a college town. You know that there are 2000 students enrolled in the school, but you don't know the population of the town (without student). You walk up and down the man streets of the town, stop people, and ask them if they are student or not. You ask 100 people, and 60 of them say they are student. Estimate the non student population of the town.
