Kentville, a community of 10,000 people, resides next to a krypton mine, and there is concern that the emissions from the krypton smelter have resulted in adverse effects. Specifically, kryptonosis seems to have killed 10 of Kentvilles inhabitants last year. A neighboring community, Lanesburg, has 20,000 inhabitants and is far enough from the smelter to not be affected by the emissions. In Lanesburg only two people last year died of kryptonosis.

 What is the risk of dying of kryptonosis in Kentville?
