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?
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?
since the maximum number of children in each family is $2,$ a family can either have $2$ girls or $1$ girl or no girl.
Hence, the required sample space is $S =\{0,1,2\}$
