3. In-class activity Suppose we want to identify the probability distribution for the number of children born to randomly selected couples. For each student in the class, find the number of brothers and sisters and record the total number of children (including the srudent) 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 born to randomly selected couples?

Explanation / Answer

This data for the distribution will not be complete because if a child is not admitted in that school then it will not be recorded.
