In this case, the events are independent because the birth of a girl or a boy does not affect the probability of obtaining a 1 by throwing a 16-sided die.
In the same way, throwing a die and obtaining the number 1 does not affect the probability that a baby is a girl or a boy.
When two events are independent then
The probability that a baby is a girl is
The probability of obtaining a 1 when casting a 16-sided die is:
Then:
