An experiment consists of recording boy – girl composition of family with 2 children,
(i) What is the sample space if we are interested in knowing whether it is a boy or girl in the order of their births?

(i) What is the sample space if we are interested in knowing whether it is a boy or girl in the order of their births?
(ii) What is the sample space if we are interested in the number of girls in the family?
(i) When the order of the birth of a girl or a boy is considered, the sample space is given by S =
{GG, GB, BG, BB}
(ii) 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}

Let B stands for boys and G stands for girl. Then
(i) Required sample space = S
= {BB, BG, GB, GG}
Required sample space = {0, 1, 2}
