![Note that 5% of the population suffers from a
particular disease. There is a diagnostic test to
identify this disease. If a person who has the
disease undergoes the test, 99% the test
becomes positive. Similarly, if a person who
does not have this disease undergoes this test,
5% the time the test becomes positive.
If a randomly selected person undergoes this
test and the test becomes positive, what is the
probability that he actually does not have the
disease? Enter your answer to the nearest

Step 1
The question is about Baye's theorem
Given :
Prob. of population suffers from disease = 0.05
Prob. of the test is positive given that a person has disease = 0.99
Prob. of the test is positive given that a person does not have disease = 0.05
To find :
A prob. that randomly selected person does not have the disease given that the test becomes positive
Step by step
