The following table shows the probabilities of some events related to this chance process: Event Probability Smokes 0.25 0.08 Smokes and gets cancer Does not smoke and does not get cancer 0.71 (a) Find the probability that the individual gets cancer given that he is a smoker. Show (b) Find the probability that the individual smokes or gets your work. cancer. Show your work. (c) Two adult males are selected at random. Find the prob- ability that at least one of the two gets cancer. Show your work.
