The 8 possible outcomes for three children are:
* ggg
* ggb
* gbg
* gbb
* bgg
* bgb
* bbg
* bbb
Of these, two girls and a boy occurs 3 out of 8 times, which is a probability of 0.375. This assumes that the probability of a boy and girl being in the family is equal, which is not entirely true for a large number of reasons.
What else can I help you with?
What is the probability that the 6 child family has exactly two girls?
The probability is 2 - 6
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 a family of 3 children has exactly 2 girls?
It is 3/8.
What is the probability of having 2 girls and 3 boys in a five child family?
1/32
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 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 a family of four children has at least 1 boy?
1 in 2
A family has 8 girls and 4 boys. A total of 2 children must be chosen to speak on the behalf of the family at a local benefit. What is the probability that 1 girl and 1 boy will be chosen?
14/33
What is the probability of having 3 baby girls in a row?
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.
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 2 girls and 3 boys in a five child family?
1/32
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
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.
In a family of 5 what is the probability that you will have 3 girls (please show your work)?
The probability of a female is approx 0.4831 across the world. If you assume (rather dubious) that the genders of children in a family are independent then the probability is approx 0.3012In a family of 5, the probability of 3 girls and 2 boys is5C3*(0.4831)3*(0.5169)2 = 0.3012
