A diagnostic test for a disease is such that it (correctly) detects the disease in 90% of the individuals who actually have the

mart [117]

Answer:

0.1552

Step-by-step explanation:

Hi!

Give a random person, lets call:

D = the person has the disease

¬D = the person doesnt have the disease

T = the test on this person is positive (detects the disease)

¬T = the test on this person is negative

We are give the conditional probabilities:

P(T | D) = 0.9

P(¬T | ¬D) = 0.9

P(D) = 0.02

From those we know that:

P(T | ¬D) = 0.1

P(¬T | D) = 0.1

We must find P(D | T). For that we use Bayes theorem:

$P(D|T) = \frac{ P(T|D)P(D)}{P(T|D)P(D) +P(T| \neg D)P(\neg D) }$

$P(D | T) = \frac{0.9*0.02}{0.9*0.02 + 0.1*0.98} = 0.1552$
