12. The condition algebritis affects 20% of college professors. The blood test for algebritis correctly identifies the condition in 99.9% of affected people and incorrectly identifies 1% of healthy people as having the condition [false positives]. Draw a tree diagram to answer the question: What percentage of college professors who test positive actually have the condition? [That is, what is the probability that a college professor is sick given that they test positive?]
