Question

A survey of needy and disabled youths showed that 52% of those who had no preschool education were arrested or charged with a crime by the time they were 19, whereas only 30% who had preschool education wound up in this category. The survey did not specify what percentage of the youths in the survey had preschool education, so let us take a guess at that and estimate that 22% of them had attended preschool. (Round all answers to the nearest 1%.)

(a) What percentage of the youths arrested or charged with a crime had no preschool education? %

(b) What would this figure be if 78% of the youths had attended preschool?

Explanation / Answer

A) 22% attended preschool, so that means 78% did not. Out of those, 52% were charged with a crime, so that would be about 41%

B) 52% of 22%, which would be about 11%.
