There are several reasons that the question cannot have a proper answer. The first is that children's gender are not independent events. It is, therefore, wrong to multiply probabilities. Second, the probability of a girl is not 1/2. Current statistics show that it is approx 0.48.
However, if you wish to ignore these relevant facts, the [incorrect] answer that is expected is 1/4.

What is the probability that in a family of four children that all four children are girls?
The probably of four girls in a family with four children is 1/16. I got this answer because: Probability of a girl is 1/2 and to get all girls you would multiply it by 1/2 for the rest of the girls.
What is the probability that a family with 4 children has at least 2 girls?
Assuming that boys and girls are equally likely, it is 11/16.
What is the probability of having exactly 2 boys out of 6 children?
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.
Theoretical probability that a family of 4 children will be all girls?
4/6=2/4 n(s)=3 6
What is the probability that a family of four children has at least 2 girls?
Going by the assumption that the probability of a child being a girl is 1/2, and that the events are independent, then the probabilities of different numbers of girls are as follows: P(0 girls) = 1/2 ^ 4 = 1/16 P(1 girl) = 4 * (1/2) * (1/2 ^ 3) = 1/4 P(2 girls) = 6 * (1/2 ^ 2) * (1/2 ^ 2) = 3/8 P(3 girls) = 4 * (1/2 ^ 3) * (1/2) = 1/4 P(4 girls) = 1/2 ^ 4 = 1/16 Therefore the probability of at least 2 girls = 3/8 + 1/4 + 1/16 = 11/16
What is the probability that a family will have a boy?
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.
What is the probability that in a family of four children that all four children are girls?
The probably of four girls in a family with four children is 1/16. I got this answer because: Probability of a girl is 1/2 and to get all girls you would multiply it by 1/2 for the rest of the girls.
What is the probability that a family of 3 children has exactly 2 girls?
It is 3/8.
What is the probability that no girls?
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.
What is the probability that a family with 4 children has at least 2 girls?
Assuming that boys and girls are equally likely, it is 11/16.
What are the chances for acouple to have 2 girls and a boy if they have 3 children?
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%.
What is the probability of a family that has 8 children 4 of them are girls?
For any particular pair of parents, the gender of their children is not 1/2 nor are the genders independent. However, if you assume that they are, and that the probability of either gender is 0.2, the probability tat 4 out of 8 are girls is 8C4*(1/2)8 = 70/256 = 0.27 approx.
Four children that is probality at least two are girls?
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 girl is approx 0.48, the probability of 2 or more girls is 0.6617.
What is the probability that a random couple with three children will have all girls?
Assuming that children of either gender are equally likely, the answer is (1/2)3 = 1/8
What is the probability of having exactly 2 boys out of 6 children?
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.
Theoretical probability that a family of 4 children will be all girls?
4/6=2/4 n(s)=3 6
What is the probability that the 6 child family has exactly two girls?
The probability is 2 - 6
