- When a sample contains 100 or more cases, what is the correct probability distribution to use?The data in the following table show the association between cigar smoking and death from cancer for 135,096 men. Note: current cigar smoker means cigar smoker at time of death. E Click the icon to view the table. (a) If an individual is randomly selected from this study, what is the probability that he died from cancer? (b) If an individual is randomly selected from this study, what is the probability that he was a current cigar smoker? (c) If an individual is randomly selected from this study, what is the probability that he died from cancer and was a current cigar smoker?
