Answer:
B. 0.03
Step-by-step explanation:
A blood test to detect prostate cancer in men gives a positive result 96% of the time if a person has prostate cancer.
This means the test detects 96% times correctly that the person has cancer. In the remaining i.e 4% times it detects incorrectly, which means the person has not cancer but he is detected that he has cancer. This is the case of false negative.
It is 97% accurate for people who do not have the disease.
This means the test detects 97% times correctly that the person doesn't have cancer. In the remaining i.e 3% times it detects incorrectly, which means the person has cancer but he is not detected that he has cancer. This is the case of false positive.
