Answer:

0.193877

Explanation:

The data given to us is

Pre-Employment Drug Screening Results

Positive test result Negative test result

Drug Use Is Indicated Drug Use Is Not Indicated

Subject Uses Drugs: 38 12

Subject Is Not a drug user: 19 29

Now the total of this is = 38+19+12+29= 98

Now the probability of false positive is = 19/98= 0.193877

The Subject Is Not a drug user would suffer from a false positive. He is not a user and has a positive result.
