Drug usage in the workplace costs employers incredible amounts of money each year. Drug testing potential employees have become so prevalent that drug users are finding it extremely hard to find jobs. Drug tests, however, are not completely reliable. To decrease the likelihood of making an error, all potential employees are screened through two tests, which are independent. One test has a 93 % accuracy and the other has a 94% accuracy. Step 1 of 2: If a person were drug free, what is the probability they would fail both tests? Round your answer to four decimal places, if necessary.
