Suppose the probability of being infected with a certain virus is 0.001. A test used to detect the virus is positive 99% of the
charle [14.2K]

Answer:

P (A ║ B)  = 1.98 %

Step-by-step explanation:

Bayes´ Theorem  express

P (A ║ B)  =  P(A) * P( B ║ A) / P(B)

Now we identify

Event A  person infected with a virus. Probability of being infected by a virus is  P/A)  0.001

Event B  the test was positive. Probability of test positive  P(B)  = 0,05

Probability of  P ( B║ A)  is the porbability of test positive given that is infected   = 0.99

Then by subtitution in a general equation of the theorem we have

P (A ║ B)  =  0.001*0.99/ 0.05

P (A ║ B)  =  0.0198          P (A ║ B)  = 1.98 %
