Assignment Submission For this assignment, you submit answers by question parts. The number of submissions remaining for each question part only changes if you submit or change the answer. Assignment Scoring Your last submission is used for your score. Based on data from a statistical abstract, only about 17% of senior citizens (65 years old or older) get the flu each year. However, about 22% 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.) What is the probability that a person selected at random from the general population is senior citizen who will get the flu this season? 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? Repeat parts (a) and (b) for a community that has 95% senior citizens. Repeat parts (a) and (b) for a community that has 48% senior citizens.

Explanation / Answer

Hello! let's go:

* what is the probability that a person selected at random from the general population is senior citizen who will get the flu this season?

(0.17)(0.14)=0.0238

* 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?

a person selected at random from the general population is a person under age 65=86%

(0.86)(0.22)=0.1892

* Repeat parts for a community that has 95% senior citizens.

(0.17)(0.95)=0.1615

a person selected at random from the general populationis a person under age 65=5%

(0.05)(0.22)=0.011

* Repeat parts for a community that has 48% senior citizens.

(0.17)(0.48)=0.0816

a person selected at random from the general populationis a person under age 65=52%

(0.52)(0.22)=0.1144
