Someone explain this to me? - a private detective figures that he has a one in ten chance of recovering stolen property for his client. the expenses for the investigation will cost him $10,000, but the recovery fee is $80,000. based only on this information, should the private detective take the job?

a) the expected value is $1,000.00, so the detective should take the job.
b) the expected value is $2,000.00, so the detective should take the job.
c) the expected value is −$2,000.00, so the detective should not take the job.
d) the expected value is −$8,000.00, so the detective should not take the job.
