Given information: A family has 2 children and one of them is a girl.

To find: Probability of the other child also being a girl.

Solution:

There are four possible outcomes when a family has two children: BB, BG, GB and GG (where B represents a boy and G represents a girl).

We know that one of the children is a girl, so the possible outcomes are BG, GB and GG.

Out of these three outcomes, only one outcome is GG (both children are girls).

Therefore, the probability of the other child also being a girl is 1/3.

Hence, the correct answer is option C.
