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.

Will the mean always be in the data set?
No. Very often the mean will not be part of the data set. In most countries, the average number of children per family is some fractional number. For example, in 2006, the mean number of children in a UK family was 1.8. However, I have yet to come across 0.8 of a child!

This family has 4 girls and 3 boys. Here is how to get the answer: Assume the family has X girls and Y boys, according to the question, we can come up with 2 equations: X-1=Y, 2(Y-2)=X. Solve the equations, we get X=4, Y=3.
Each child in a family has at least three brothers and two sisters What is the smallest number of children the family might have?
Some families have only one child or two at the most because either with one child they could not have more children or didn't want more children and many families feel two children is enough.
Each child in a family has at least 5 brothers and 3 sisters What is the smallest number of children the family might have?
8 The answer is 9. If you are a boy, it would be 6 boys and 3 girls, but it you were a girl it would be 5 boys and 4 girls because you cannot be your own brother or sister. 10, the combination of 6 brothers and 4 sisters. Then each is guaranteed to have 5 brothers, 3 sisters. In the examples for 9 total, the girls in 6-3 would only have 2 sisters, and vice versa for the boys in 5-4. It seems 9 is the correct answer for the way the question is worded. If the question were worded "What is the least number of of children that would guarantee that each child has five brothers and three sisters ?" then 10 would be correct.

If Sophie has 5 more brothers than sisters and her brother Joe has half as many sisters than brothers how many children in the family?
Suppose there are B boys and G girls. Then Sophie has B brothers and (G-1) sisters - remember to leave Sophie out. So B = (G-1) + 5 ie B = G + 4 Also Joe has (B-1) brothers and G sisters So (B-1) = 2*G Substituting the value of B from Sophie's equation into this one gives (S+4 - 1) = 2*G ie G+3 = 2*G Subtract G from both sides: 3 = G and then B = G+4 = 7 So number of children in the family = B+G = 7+3 = 10.
If your youngest sister has the same number of brothers and sisters and her oldest brother has twice as many sisters as brothers how many kids are in the family?
Let the number of sisters be s and the number of brothers b. We must remember to bear in mind that no one is their own brother or sister! 'The youngest sister has the exact same number of brothers and sisters.' Therefore: s - 1 = b 'Her oldest brother has twice as many sisters as brothers.' So: 2(b - 1) = s 2b - 2 = s Subtracting 1 from each side: 2b - 3 = s - 1 But s - 1 = b, so 2b - 3 = b b - 3 = 0 b = 3 And from above, s = 4. Thus there are seven siblings altogether; Four girls, 3 boys.
