Notably, the probability that an individual died from cancer (0.63%) is relatively low, which might be expected in a general population sample. However, the probability that an individual was a current cigar smoker (4.4%) is higher than the cancer death rate, suggesting that smoking is a prevalent behavior within this group. Moreover, the probability that an individual both died from cancer and was a current cigar smoker (0.14%) reflects the increased risk associated with smoking. Finally, the combined probability (4.99%) indicates the proportion of individuals who either died from cancer or were current cigar smokers, highlighting the significant impact of smoking on cancer mortality.<\/p>\n\n\n\n<p>These findings underscore the strong association between tobacco use and cancer, reinforcing the importance of smoking cessation programs and public health initiatives aimed at reducing tobacco consumption.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Died from Cancer Did Not Die from Cancer Never smoked cigars 620 123,094 Former cigar smoker 54 7,161 Current cigar smoker 193 5,839 (a) If an individual is randomly selected from this study, what is the probability that he died from cancer?
