The employee takes the first test, with 95% accuracy. If he’s drug free, he has 95% probability to pass the test. 95% = 95/100 = 0.95
Then the employee takes the second test, also with 95% accuracy. If he’s drug free, he has 5% probability to fail the test. 5%=5/100=0.05
Joint probability is calculated like this: probability 1*probability 2.
In this case, joint probability = 0.95*0.05 = 0.0475
which means 4,75%
