Question
An experiment consists of recording boy-girl composition of families with 2 children. What is the sample space if we are interested in the number of girls in the family?
Solution
Sample space, if we are interested to know the number of girls in the family:
It is 0, if the outcome is BB in sample space of part (i)
It is 1, if the outcome in BG or GB in sample space of part (i)
It is 2, if the outcome is GG in sample space of part (i)
Hence, the sample space is S = {0, 1, 2}
