Based on data from the Statistical Abstract of the United States, 112th Edition, only about 14% of senior citizens (aged 65 years older) get the flu each year. However, 24% of the people under 65 years old get the flu each year. In the general population, 12.5% are senior citizens. a.) What is the probability that a person selected at random from the general population is a senior citizen who gets the flu this year? 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?
