Respuesta :

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.
