Question 53547
A medical research is studying the spread of a virus in a population of 1000 mice. During any given week there is an 80% probability that an infected mouse will overcome the virus, and during the same week there is a 10% probability that a noninfected mouse will become infected. one hundred mice are currently infected with the virus. How many will be infected next week? In 2 weeks?
---------------------
Start:--------------Infected = 100-------------Healthy=900

End 1st-------------Infected=100-80+90=110 ;  Healthy=900+80-90=890

End 2nd-------------Infected=110-88+89=111 ;  Healthy=890+88-89=889
