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. in a given population, 3.5% of the people actually have the disorder.
the probability that a randomly chosen person tests negative is

0.07%

Step-by-step explanation:

3.5/100 * 2/100 = 7/10000 = 0.0007 = 0.07%

0.93675

Step-by-step explanation:

98% accurate for those who have the disease, which means receiving a positive result.

97% accurate for those who don't have the disease, which means receiving a negative result.

3.5% of people have the disease, which means 96.5% of people do not.

98% of 3.5% = 3.43% of people receive true positive results, so 0.07% of people receive false negative results.

97% of 96.5% = 93.605% of people receive true negative results.

0.07% false negative results + 93.605% true negative results = 93.675% negative results in all.

93.675% = 0.93675 probability that a randomly chosen person tests negative.
