What is the probability that a family of 3 children has exactly 2 girls?
It is 3/8.
What is the probability of getting 3 girls in a family of 10 children?
The probability of exactly 3 girls in a family of 10 children, assuming equal chance of a boy or girl, is 0.1172. This is a binomial distribution.
What is the probability of having 2 girls and 3 boys in a five child family?
1/32
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 of a child being a boy?
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!

What is the probability of randomly selecting a three-child family with exactly two girl children?
2/6 is not accurate. using a theoretical method for equally likely outcomes, there are 2 possible outcomes for each birth: either a boy(B), or a girl (G). For a family of three children, the total number of possibilities (birth orders) is 2*2*2=8 to double check this work, here are the eight possible outcomes:BBB, BBG, BGG, GBB, GBG, GGB, and GGG. You want EXACTLY two girls, this assumes that the other must be a boy. Therefore, the probability that a three child family has 2 girls one boy is P(2 girls)=3/8=0.375

When a family of seven boys and no girls is expecting an eighth child what is the probability of the next child being a girl?
If the gender of a child were an independent variable then the genders of the existing children would be irrelevant and so the probability of the next child being a girl would be approximately 1/2.It would be approximately 1/2 because the overall proportion is not exactly half. However, and more important, is the fact that the gender of a child is affected by the parents' genes and so is not independent of the gender of previous children.
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.
If a family has three children find the probability that two of the children are girls?
there is a 50% chance that two of them will be girls
What is the probability of a family having a boy after four girls?
The probability of a boy is still 0.5 no matter how many prior children there are.
What is the probability if a girl is expecting her 10Th child if rest 9 are girls?
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.
The probability that a family with 3 children has 3 girls assuming that having boys and girls are equally likely?
50%
