Based on data from a statistical abstract, only about 12% of senior citizens (65 years old or older) get the flu each year. However, about 23% of the people under 65 years old get the flu each year. In the general population, there are 14% senior citizens (65 years old or older). (Round your answers to three decimal places.) (a) What is the probability that a person selected at random from the general population is a senior citizen who will get the flu this season? (b) What is the probability that a person selected at random from the general population is a person under age 65 who will get the flu this year? (c) What is the probability that a person selected at random from a community that has 90% senior citizens is a senior citizen who will get the flu this season? (d) What is the probability that a person selected at random from a community that has 90% senior citizens is a person under age 65 who will get the flu this year? (e) What is the probability that a person selected at random from a community that has 55% senior citizens is a senior citizen who will get the flu this season? (f) What is the probability that a person selected at random from a community that has 55% senior citizens is a person under age 65 who will get the flu this year?
