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 4 boys and 1 girl out of 5 children is 0.1724 approx.

What is the probability that a couple with 3 children will have at least 1 girl?
The easiest way of calculating this is to find the probability that all three are boys, as this is the only arrangement that does not fit the criteria. Then work out the answer by taking this away from 1. Probability that all three are boys = 1/2 x 1/2 x 1/2 = 1/8. probability of there being at least one girl is 1 - 1/8 = 7/8 or 87.5%
A woman has 5 children 1 girl and 4 boys What is the probability that her next child will be a girl?
50%, the Father's contribution decides the sex of a child.
In a classroom the students are 11 boys and 1 girls If one student is selected at random find the probability that the student is a girl?
1/12 =0.08333... ≈ 8.3%
What is the probability of 4 boys in a family with 4 children?
In a family with four children, the probability of having four boys is 1 in 16.
A women is going to have 6 children What is the probability that all 6 will be boys?
if we assume that the probability for a girl being born is the same as a boy being born: (1/2)^6 = 0.015625 = 1.5625%

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.
Probabilty of having 12 boys and 1 girl?
Assuming the probability of having a boy is 1/2, and that the probabilities are independent: Probability of 1 girl and 12 boys = (1/2)13 * 13 = 0.001587..., which is around 1/630
What is the probability of having 2 boys and 1 girl with triplets?
3/8
In a classroom the students are 11 boys and 1 girl if one student is selected at random find the probability that the student is a girl?
There is only one girl out of 12 students so the probability that the girl is selected is 1/12.
What is the probability that a family of 4 would have 3 boys and 1 girl?
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 three boys and a girl is 0.2669.

What is the probability of having 3 boys for 4 kids?
Assuming probability of having a boy is P(B) = 1/2, and of having a girl is P(G) = 1/2,the probability of having 3 boys for 4 kids (with out regard to the girl to be the first,second, third or fourth kid) is;P(3B1G) = 4C3 [P(B)]4 = 4 (1/2)4 = 0.250 = 25%The factor 4 comes because there are 4 possibilities for the order in which the girl cancome out.
