The probability is 2 - 6
The probability of a boy is still 0.5 no matter how many prior children there are.
Since having a child to a child is an independent event (assuming no outside intervention), the probability is still about 50 / 50 boy or girl.
We would need to know the number of children in the family to answer this question. For instance, the probability of having no girls in a family of two children would be 1/4 theoretically. In general it is 2-n where n is the number of children.
The odds of a four-child family having four boys can be calculated using the probability of each child being a boy, which is typically 1/2. Therefore, the probability of having four boys in a row is (1/2) × (1/2) × (1/2) × (1/2) = 1/16. This means the odds against having four boys are 15 to 1, as there are 15 other combinations of boys and girls possible in four children.

The probability is1 - [Prob(No children) + Prob(1 child, a girl) + Prob(2 children, both girls) + Prob(3 children, all girls) + ...]Not all relevant information is readily available.
The chances of a couple having 2 girls and 1 boy among 3 children can be calculated using the probability of each combination. Assuming each child is equally likely to be a boy or a girl, the probability of having 2 girls and 1 boy is given by the binomial probability formula. There are three possible arrangements for 2 girls and 1 boy (GGB, GBG, BGG), making the probability approximately 3 out of 8, or 37.5%.
Assuming that the probability of having a baby girl is 1/2 and that of having a baby boy is 1/2, the probability of having 3 baby girls in a row is (1/2)(1/2)(1/2)=1/8.
you have a 75% chance
It depends on the context: if you select a child at random from a girls' school, the probability is 0, while if it is at a boys' school it is 1!
