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?

Option A

Option B

Option C

Option D

Solution

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 $S =\{0,1,2\}$

A box contains $1$ red and $3$ identical white balls. Two balls are drawn at random in succession without replacement. Write the sample space for this experiment.
