प्रश्न
An experiment consists of boy-girl composition of families with 2 children.
What is the sample space if we are interested in the number of boys in a family?
उत्तर
Since the maximum number of children in each family is two, a family can either have two boys or one boy or no boy.
Hence, the required sample space is given by
S = {0, 1, 2}
