# Thread: probability problem

1. ## probability problem

Hi I was wondering if anyone could help me with this problem.

Only about 14% of senior citizens get the flu each year. However, about 24% of people under 65 years old get the flu each year. The general population consists of 12.5% senior citizens.

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 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?

Any help would be greatly appreciated.

a) $(\frac{12.5}{100})(\frac{14}{100})$

b) $(\frac{88.5}{100})(\frac{24}{100})$
