Unformatted text preview: 6.042/18.062J Mathematics for Computer Science November 17, 2010 Tom Leighton and Marten van Dijk Problems for Recitation 18 1 Nerditosis There is a rare and deadly disease called Nerditosis which afflicts about 1 person in 1000. One symptom is a compulsion to refer to everything fields of study, classes, buildings, etc. using numbers. Its horrible. As victims enter their final, downward spiral, theyre awarded a degree from MIT. Two doctors claim that they can diagnose Nerditosis. 1. Doctor X received his degree from Harvard Medical School. He practices at Mas- sachusetts General Hospital and has access to the latest scanners, lab tests, and re- search. Suppose you ask Doctor X whether you have the disease. If you have Nerditosis, he says yes with probability 0.99. If you dont have it, he says no with probability 0.97. Let D be the event that you have the disease, and let E be the event that the diagnosis is erroneous. Use the Total Probability Law to compute...
