Assume there аre а tоtаl оf fоur sufficient causes for Disease Y. Disease can occur with component causes A, B, C, and D together. In the absence of exposure B, component E must be present to cause disease. It is also known that exposure to component causes C and F together can cause disease. Finally, exposure to just component cause G can cause disease. 1f. Now, assume that in a second population, Population 2 (which has the same four sufficient causes), 15% of the population is exposed to factors A, C, and D; 30% of the population is exposed to factors C and F, and 25% of the population is exposed to factor E. Again, everyone is exposed to B. What is the difference in the risk if exposed to B and the risk if unexposed to B? What is the ratio of the risk if exposed to the risk if unexposed? [Please provide your calculations. Round all values to two decimal places (e.g., 0.00)]
