8. The Bureau of Justice conducted a study of 272,111 former inmates released from prisons in 15 states in 1994. A classification of the former prisoners by "most serious offense for which released" yielded the following: 22.5% violent, 33.5% property, 32.6 % drug, 11.4% other. Of those prisoners whose most serious crime was violent 61.7% were rearrested within 3 years of release. For other categories, the recidivism rate (defined as rearrested within 3 years of release) were: property 73.8%, drug 66.7%, and other 62.6%. If a released prisoner from these 15 states is rearrested within 3 years of release, what is the probability that this prisoner's most serious offence was violent?
