A certain disease has an incidence rate of 0.5%. The false negative rate on a test for the disease is 5%; the false positive rat
expeople1 [14]

Using conditional probability, it is found that the probability a person who tests positive actually has the disease is 0.087 = 8.7%.

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which:

  • P(B|A) is the probability of event B happening, given that A happened.
  • P(A \cap B) is the probability of both A and B happening.
  • P(A) is the probability of A happening.

For this problem, the events are given as follows:

  • Event A: Positive test.
  • Event B: Person has the disease.

The percentages associated with a positive test is:

  • 95% of 0.5%(person has the disease).
  • 5% of 99.5%(person does not have the disease).

Hence:

P(A) = 0.95 x 0.005 + 0.05 x 0.995 = 0.0545.

The probability of both a positive test and having the disease is:

P(A \cap B) = 0.95 \times 0.005 = 0.00475

Hence the conditional probability is:

P(B|A) = 0.00475/0.0545 = 0.087.

The probability a person who tests positive actually has the disease is 0.087 = 8.7%.
