Random sampling

Of all the women in the world who have exactly two kids, imagine the subgroup of this group consisting of women in which at least one of their two children was male. Question: if one of these women from the latter group was chosen, what would be the chance that both of her kids were male?

1/3 because if one is male there are three possibilities: mw, wm, mm.
