Suppose we want to identify the probability distribution for the number of children in families with at least one child. For each student in the class, find the number of brothers and sisters and record the total number of children (including the student) in each family. Construct the relative frequency table for the result obtained. (The values of the random variable x will be 1, 2, 3, . . . .) What is wrong with using this relative frequency table as an estimate of the probability distribution for the number of children in randomly selected families?
