if you take 100 people, and expose them to the bacteria that causes leprosy, on average, only 5 of them will actually get the disease. this is crazy because when i walked into a room of leprosy patients and the person showing us around told us that the disease is transmitted through the air, i'm pretty sure all 5 of us students freaked out on the inside, when in actuality we were probably pretty safe.
why is it that when everyone is exposed to the same thing, only so few get it?
