On the planet of Dagobah, Swamp Disease is a rare, but very serious and debilitating condition. Identifying persons who have Swamp Disease is incredibly important for public health planning purposes. With proper therapy and disease management, adults living with Swamp Disease can live very long and meaningful lives. Since the population of Dagobah is fairly small, in 2010 it was decided that annual population-based surveillance and monitoring of Swamp Disease on Dagobah should be conducted. During the first year of surveillance in 2010, n=3 adults were known to be living with Swamp Disease among the 500 inhabitants of this planet. For the next 9 years, or through the end of 2019, 2 cases of Swamp Disease have been identified every year in Dagobah - a planet that no one voluntarily moves to or leaves... (Let's also assume, for simplicity, that there are no births or deaths during this period.)

(a) What is the prevalence of Swamp Disease in 2019?

Shouldnt the answer be (18/500)* 100 or should it be (2/500) *100?
