Answer: Pr(test positive ) = 0.38.
Step-by-step explanation:
Since we have given that
Probability of getting a certain disease = 0.2
Probability of not getting a certain disease = 1-0.2 = 0.8
Probability that test turns a positive results for those with the disease = 90% = 0.90
Probability that turns a negative results for those without diseases = 75% = 0.75
Probability that turns a positive results for those without diseases = 1-0.75=0.25
So, Probability of test positive is given by
P(having diseases) . P(test positive) + P(not having diseases) . P(test positive)
Hence, Pr(test positive ) = 0.38.
First you start with multiplication 4+(2x5) with is= 10
then you add 4+10 = 14
