The case fatality rate (percent dying of disease once diagnosed) for Ebola virus disease (EVD) varies between 25% to 90%. Assume an entire classroom of 32 students were exposed and were diagnosed with EVD. Assuming the worst case scenario, use a case fatality rate of 90% to answer the following questions: What is the expected number of people to die from EVD in this sample? What is the probability that only one person will survive (i.e. the probability that 31 people will die)? What is the probability that at most 28 people die from EVD in this sample? *Enter answer with at least 2 decimal places for this question. For example, if asking about age, a hypothetical answer could be 68.37.
