In the general population, there are10%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 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) Repeat parts (a) and (b) for a community that has89%senior citizens.

• (a)
• (b)

(d) Repeat parts (a) and (b) for a community that has46%senior citizens.
