(1) Suppose you are a physician and have examined a patient whom you believe has a 30% chance of having deep venous thrombosis (clots in the veins of the leg). You decide you will treat the patient with anticoagulants (blood thinners) if further testing increases his probability of disease to 85% or more. Similarly, you will send the patient home without treatment if you can reduce his probability of disease to less than 10%. You have a choice of 2...
