In a study of 474,508 cell phone​ users, it was found that 197 developed cancer of the brain or nervous system. Assuming that cell phones have no​ effect, there is a 0.000472 probability of a person developing cancer of the brain or nervous system. We therefore expect about 224 cases of such cancer in a group of 474,508 people. Estimate the probability of 197 or fewer cases of such cancer in a group of 474,508 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous​ system? ​(a) ​P(x≤197​)=
