The answer depends on whether the children are picked at random. If they were selected from inside a girls' school the probability should be quite close to 0. Likewise, if the children were picked inside a boys' school.
If six children are picked at random from a large group of children with an equal number of boys and girls, then the answer is
6C2*(1/2)6 = 15/32 = 0.47, approx.

What is the probability of having three girls and zero boys?
Assuming that having boys and girls are equally likely, then the probability is 1/8. * * * * * You also need to assume that the children's genders are independent. They are NOT and depend on the parents' ages and genes.
What will be the probability of 4 sons to a couple?
Since the probability of having a son is about 1/2, the probability of the first 4 children being boys is about (1/2)4.

What is the probability of a 13 child family having 13 boys?
There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes. However, if you assume that they are independent events then, given that the probability of a boy is approx 0.52, the probability of 13 boys in a family with 13 children is approx 0.00019.
What is the probability of exactly 7 boys in 10 births when the birth of any child does not affect the probability of the gender of any other children?
This is a Binomial Probability; p=0.5, n=10 & x=7. Since you want the probability of exactly 7, in the related link calculator, after placing in the above values, P(x=7) = 0.1172 or 11.72%.
What is the probability of having 4 boys in 10 births?
25
What are chances of having additional boys as children when your first born is a boy?
There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes.However, if you assume that they are independent events then, the probability of a second boy is approx 0.52, the probability that the next two are boys is (0.52)^2 and so on.
