According to Engineering News-Record (Dec. 1, 1983), the District of Columbia is now mandating that
at least one-half of all the jobs created by city contracts be filled by local residents. Suppose you want to survey jobs created by city contracts after the mandate was issued to determine the level of compliance with the new law. If in fact only 40% of all jobs created by city contracts are filled by local residents:
a) What is the expected number of jobs you would have to survey before you find one that has been
filled by a local resident?
b) What is the probability that you will not find a job filled by a local resident until after the fourth job
surveyed?
