What is your chance of getting a cold or the flu? Annually, about 25% of the U.S. population gets a cold and between 35 - 50% gets the flu, but both illnesses are highly age-related. In 1994, for the 5-24 age group, 32.7 million of 74.8 million got the flu. For people 45 years of age and older, 18.8 million of 81.7 million got the flu.
Calculate the same probability for the 45-and-older group.
