Chapter 8.5, Problem 27MS

Sploosh test (H). Given the scenario in the previous Mindscape, one way to enhance the diagnosis is to test the blood for sploosh. Studies have shown that among people who have disease A, 20% have sploosh in their blood; among people with disease B, 50% have sploosh; among people with dise ase C, 10% have sploosh; and among people with neither disease A, B, nor C, 30% have sploosh. Suppose there are 1000 people with symptoms identical to yours. How many of those with disease A have sploosh? How many of those with disease B have sploosh? How many of those with disease C have sploosh? How many of those with neither disease A, B, nor C have sploosh?
