Hi, 

Imagine that 10% of the population has a disease. There is a test that determines if you have the disease, but it's only 60% accurate for those who do have the disease, with about a 10% false positive rate (e.g. those who do not have the disease will test positive).

Suppose you were tested positive -- how likely is it you have the disease?
