The percentage of coronavirus (COVID-19) infected people in a certain city is 15%. Suppose that we randomly select a sample of 6 people from this city. a) Find the probability that there will be one infected person in the sample. b) Find the expected number of infected people in the sample (E(X) = ?). c) Find the variance of the number of infected people in the sample (? 2 )

Let P(t) represent the number of people who, at time t, are infected with a certain disease. Let N denote the total number of people in the population. Assume that the spread of the disease can be modeled by the initial value problem: dP/dt = k(N − P)P, P(0) = P0. At time t = 0, when 100,000 member of a population of 500,000 are known to be infected, medical authorities intervene with medical treatment. As a consequence of this...
