8. In the period of 2010 - 2020 in the United States 1/3 of patients 55 years old or older had a seasonal flu vaccine. The risk of death for a flu-vaccinated person 55 years or older in the following 10 months is 0.6 deaths per 1,000 flu-vaccinated persons 55 years old or older. The risk of death for a non-vaccinated 55 year old or older person in the same 10 month period is 5 deaths per 1,000. Given these numbers, what is the probability that a person 55 years or older in the United States will survive 10 months into that year's flu season?

In the period of 2010 – 2020 in the United States 1/3 of patients 55 years old or older had
a seasonal flu vaccine. The risk of death for a flu-vaccinated person 55 years or older in the
following 10 months is 0.6 deaths per 1,000 flu-vaccinated persons 55 years old or older. The
risk of death for a non-vaccinated 55 year old or older person in the same 10 month period is
5 deaths per 1,000. Given these numbers, what is the probability that a person 55 years or
