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

The probability that a randomly chosen person tests positive is 0.06325
Step-by-step explanation:
if we chose a person randomly and the test is positive, there are two possibilities:
1. The person actually have a disease: the probability of this case is given by the multiplication of the probability of having the disease and the probability that the test detect the disorder. That can be written as:
0.035*0.98=0.0343
where 0.98 is the probability that the test detect the disease given that a person have a disease.
2. The person doesn't have a disease: the probability of this case is given by the multiplication of the probability of doesn't have the disease and the probability that the test said that the person have the disorder. That can be written as:
0.965*(1-0.97)=0.02895
Where (1-0.97) is the probability that the test detect the disease given that a person don't have a disease.
Finally the probability that a randomly chosen person tests positive is the sum of both cases and it calculated as:
P=0.0343+0.02895=0.06325
Ответ:
y = x+2
Step-by-step explanation:
Using process of elimination, you can look at the tables and see which one prints the correct coordinates, and which ones that don't. Looking at y=2x, you can see that the first point is (-2, -4), in which the line doesn't cross, eliminating that answer. Now looking at y = x - 2, the table shows that the 1st point is (0, -2) which the line also doesn't touch. As you can see, y = x - 2 repeats itself, and earlier we saw that the table didn't match up. This leaves y = x+2 as your answer.
