(ii) What is the sample space if we are interested in the number of girls in the family?


(i) Suppose in a family of 2 children the first child born is a boy and the second child is also a boy then we denote this outcome by an ordered pair (B, B) and so on.

The sample space is given by:

S = {(B,B), (B, G), (G, B), (G, G)}

(ii) Suppose in a family there is no girl then we denote this outcome by 0 and so on.

The sample space is given by S = {0, 1, 2}
