Answer:
Step-by-step explanation:
where is the probability of success (finding a job filled by a local resident), and is the probability of failure (not finding a job filled by a local resident).
To find the expected number of jobs you would have to survey before finding one that has been filled by a local resident, we calculate the reciprocal of the probability of finding the first success:
Therefore, you would expect to have to survey approximately 2.5 jobs before finding one that has been filled by a local resident.
