Probability of having two girls in a family of two children
The probability of the other child being a girl when it is known that one child is a girl can be calculated by considering all the possible outcomes.
- There are four equally likely possibilities for the gender of two children in a family: boy-boy, boy-girl, girl-boy, and girl-girl.
- Since we already know that one child is a girl, we can eliminate the boy-boy possibility, leaving us with three equally likely outcomes: boy-girl, girl-boy, and girl-girl.

Calculation of the probability
- Out of the three remaining equally likely outcomes, only one outcome is where both children are girls (girl-girl).
- Therefore, the probability of the other child also being a girl is 1 out of 3, or 1/3.
Therefore, the correct answer is C. 1/3.
