In 1994, California passed a three-strikes sentencing law man- dating that defendants convicted of a third felony should serve a state prison term of 25 years to life. The density histogram in Fig. 28 describes the ages (in years) of third-strike felons in California€™s state prison population as of September 30, 2012.

a. Find the probability that a third-strike Californian felon randomly selected on September 30, 2012, was between 30 and 69 years of age, inclusive.
b. Find the probability that a third-strike Californian felon randomly selected on September 30, 2012, was younger than 30 years OR at least 70 years of age. Some of the bars have been left blank on purpose.
c. Find the probability that a third-strike Californian felon randomly selected on September 30, 2012, was between 30 and 39 years of age, inclusive, OR between 60 and 69 years of age, inclusive.
d. Nearly 120,000 inmates are jailed in California prisons meant to hold 84,000 inmates On November 6, 2012, California passed a proposition allowing third-strike felons to apply for reduced sentences, provided that their third offense was not violent or serious. More than 2800 prisoners may be able to reduce their sentences If all 2800 prisoners were released, would that do much to reduce the overcrowding in California prisons?
