All interns for Comcast are required to be tested for drug use. The imperfect test gives positive results (indicating drug use)

lakkis [162]

Answer:

0.0224 or 2.24%

Step-by-step explanation:

The probability that an intern uses drugs, given that the test is negative, is determined by the probability of false negative divided by the probability of a negative (true or false).

A false negative occurs when an intern who uses drugs (10%) takes the test and gets a negative. Since the test gets it right 80% of the time, the probability of this happening is:

$P(FN) = 0.10*(1-0.80)=0.02$

A true negative occurs when an intern who does not use drugs (90%) takes the test and gets a negative. Since the test gets it wrong 3% of the time, the probability of this happening is:

$P(TN) = 0.90*(1-0.03)=0.873$
