## Smoking problem¶

According to the CDC, "Compared to nonsmokers, men who smoke are about 23 times more likely to develop lung cancer and women who smoke are about 13 times more likely.''

Also, among adults in the U.S. in 2014:

Nearly 19 of every 100 adult men (18.8%) Nearly 15 of every 100 adult women (14.8%)

Exercise: If you learn that a woman has been diagnosed with lung cancer, and you know nothing else about her, what is the probability that she is a smoker?
