In a study of 421,838 cell phone users, it was found that 167 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000403 probability of a person developing cancer of the brain or nervous system. We therefore expect about 171 cases of such cancer in a group of 421,838 people. Estimate the probability of 167 or fewer cases of such cancer in a group of 421,838 people.
