Question
Exercise 7. Avian flu is a disease transmitted to humans from birds, and is of global concern. Untreated, it has a mortality rate of 60%, meaning that the probability that a given individual who catches the avian flu dies with probability p = 0.6. In a given city, 20 individuals catch the avian flu. (a) Explain why it makes sense why the number of individuals who survive could be modeled using a binomial random variable. (b) Assuming the individuals are untreated, calculate the expected number who will survive. (c) Calculate the probability that at least one individual survives the disease. (d) Under a new treatment, at least 15 of the 20 individuals survive. Calculate the probability that we would see so many individuals surviving, if the mortality rate were p = 0.6.
