2. In a study of 437 comma 485 cell phone​ users, it was found that 54 developed cancer of the brain or nervous system. Assuming that cell phones have no​ effect, there is a 0.000168 probability of a person developing cancer of the brain or nervous system. We therefore expect about 74 cases of such cancer in a group of 437 comma 485 people. Estimate the probability of 54 or fewer cases of such cancer in a group of 437...
