Based on data from a statistical abstract, only about 13% of senior citizens (65 years old or older) get the flu each year. However, about 30% of the people under 65 years old get the flu each year. In the general population, there are 12% senior citizens (65 years old or older). (Round your answers to three decimal places.)

(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) Repeat parts (a) and (b) for a community that has 88% senior citizens.
