In the 1950s, a study of 544 adult Americans who died of lung cancer found that 537 were smokers. (Let S be adult American smokers at the time of the study and let L be death due to lung cancer.) State this result as a probability: = The same study claimed that 62.2% of adult Americans smoked. State this result as a probability: = The same study claimed that 1% of adult Americans would die of lung cancer. State this result as a probability: = Find the probability that adult American smokers in the 1950s would die of lung cancer: = Find the probability that adult American nonsmokers in the 1950s would die of lung cancer: = A smoker is times more likely to die of lung cancer than a non-smoker. Does this show that smoking causes lung cancer?
