Are you asking for the probability that the other two children are male?
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
Approx. 1/2 * 1/2 = 1/4
The probabilities are not exactly 1/2.
A family has 3 children. Their first child was a girl. What I'd the probability that the two children are of different gender?
