A2 A sample of 10,000 cells are sampled from a patient. If the patient is pre-cancerous we can expect 0.1% of them to be abnormal, and otherwise we'd expect none of them to be abnormal. About 1% of patients sent for this test are actually pre-cancerous. A test is used to check cells for abnormality: the test is correct 99.5% of the time on both normal and abnormal cells. Three (3) cells have this test applied to them, and the test says one of them is abnormal and the rest are normal. What is the probability that the patient is pre-cancerous?

Question
A2
A sample of 10,000 cells are sampled from a patient. If the patient is
pre-cancerous we can expect 0.1% of them to be abnormal, and
otherwise we'd expect none of them to be abnormal. About 1% of
patients sent for this test are actually pre-cancerous. A test is used to
check cells for abnormality: the test is correct 99.5% of the time on
both normal and abnormal cells. Three (3) cells have this test applied
to them, and the test says one of them is abnormal and the rest are
normal. What is the probability that the patient is pre-cancerous?
