Abstract

Scientists have made new discoveries about a strange low-level disease. The disease is highly correlated with a particularly gene. 25% of the population has this gene. 90% of those with the gene develop the disease. Among the 75% majority, on the other hand, only 10% develop the disease. There is also a mysterious skin rash which can only occur in people who have the disease. Among the people who have the gene and develop the disease, 90% show the rash. Among the people without the gene that develop the disease, only 10% show the rash.
