In a Study Performed by the Statistics Classes at Washington

Essay

In a study performed by the statistics classes at Washington High School, city parking
spaces were examined for compliance with the requirement to put money in the
parking meters. Overall, the students found that 76% of metered parking places had
meters that were not expired, and 24% had meters that were expired. If the traffic
officer in charge of ticketing checks meters at random, what is the probability he or
she will find an expired meter before the 3rd one checked?
