A rare form of malignant tumor occurs in 11 children in a​ million, so its probability is 0.000011. Four cases of this tumor occurred in a certain​ town, which had 15,413 children.   a. Assuming that this tumor occurs as​ usual, find the mean number of cases in groups of 15,413 children. b. Using the unrounded mean from part ​(a​), find the probability that the number of tumor cases in a group of 15,413 children is 0 or 1. c. What is the probability of more than one​ case? d. Does the cluster of four cases appear to be attributable to random​ chance? Why or why​ not?
