- The national department of epidemiology has calculated the frequency with which flu patients arrive at the country's hospitals. The probability that a patient arrives with the flu is 0.1. Taking into account that the causes of the flu are many in a tropical country, what is the probability that three patients admitted to a hospital all suffer from the flu? What is the correct? A). Because the statistic is national, the probability is 0.3 since the observations can be taken as independent. B). The probability remains at 0.1 since they are independent events, both the flu and the patients. C). The probability is 0.001 since the observations can be taken as independent, since a flu can appear for many reasons throughout a country. D). The conditional probability of receiving a patient with the flu is required given that the first one to arrive had it, therefore it is not possible to calculate the probability.Assume this year's flu vaccine has a 80% chance of being effective.
