A survey of needy and disabled youths showed that 45% of those who had no preschool education were arrested or charged with a crime by the time they were 19, whereas only 34% who had preschool education wound up in this category.

(a) What percentage of the youths arrested or charged with a crime had no preschool education?________ %(b) What would this figure be if 89% of the youths had attended preschool?________ %
