In a certain year, 14,498 professional train pushers are diagnosed with carpal tunnel. The top cities for such diagnoses are Tokyo with 2,171, Osaka with 2,037, and Kyoto with 1,664. If a professional train pusher recently diagnosed with carpal tunnel is randomly selected, what is the probability that they are from somewhere other than Tokyo, Kyoto or Osaka?

In a study of 235,722 cell phone users, it was found that 109 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000477 probability of a person developing cancer of the brain or nervous system. We therefore expect about 113 cases of such cancer in a group of 235,722 people. Estimate the probability of 109 or fewer cases of such cancer in a group of 235,722 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(x ≤ 109) = (Round to four decimal places as needed.)
