The test to detect the presence of strep throat is 98% accurate for a person who has a disease and 97% accurate for person who does not have the disease. If 3.5% of the people in a given population actually have strep throat, what is the probability that a randomly chosen person test positive?

The probability that a randomly chosen person test positive is 0.06325

Step-by-step explanation:

 Let T denotes the test and D denotes the disease

We are given that The test to detect the presence of strep throat is 98% accurate for a person who has a disease

We are also given that 97% accurate for person who does not have the disease.

So,

Now we are given that 3.5% of the people in a given population actually have strep throat,

So,P(D)=0.035

Now we find :

Hence the probability that a randomly chosen person test positive is 0.06325

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
