Scientists study the condition by looking at whether or not the person has a an elevated white cell count and whether or not they have the disease. It is found that 22% of the people tested have an elevated white cell count and have ACD. Given that a person has ACD, there is an 85% chance that he/she has an elevated white cell count.
What is the probability that someone has ACD?
