 Hello and how are you all? Today my name is Priyanka and I shall be helping you with the following question. Here in this question it says an experiment consists of recording boy girl composition of family with two children. The first part which we need to answer is what is the sample space if we are interested in knowing whether it is a boy or girl in the order of their birth. And the second part of the question says what is the sample space if we are interested in the number of girls in the family. So first of all let the boy and the girl be denoted as B and G. Now here in each family there are two children. So the possible outcomes are whether there can be two boys in the family or one boy and then girl or firstly girl and then boy or two girls in a family. So this is the required sample space for the first part. Whereas when we are interested in the number of girls in the family then either there will be no girl in the family like in the first case or there can be one girl or at most two girls in a family. So the required sample space will be 0, 1, 2 containing elements 0, 1, 2. So hope you liked the question and enjoyed it too. Have a nice day.
