- How to resolve the ambiguity in the Boy or Girl paradox?
There's no paradox here, just ambiguity We're giving a vague description of a "real life" situation, and you're supposed to turn that into a well defined probability space in which to express events and their probabilities This is often hard or impossible to do, with the only possible conclusion being "some assumptions are missing" In this "boy and girl" problem, there is additional
- probability - What is the expected number of children until having at . . .
Source: (Harvard Statistics 110: see #17, p 29 of pdf) A couple decides to keep having children until they have at least one boy and at least one girl, and then stop Assume they never have twi
- Expected number of ratio of girls vs boys birth - Cross Validated
Thanks to the answers I now understand why the ratio would be 1:1, which originally sounds counter intuitive to me One of the reason for my disbelief and confusion is that, I know villages in China have the opposite problems of too high of boys:girls ratio I can see that realistically, couples won't be able to continue to procreate indefinitely until they get the gender of child they want

- probability - What is the expected number of children until having the . . .
A couple decides to keep having children until they have the same number of boys and girls, and then stop Assume they never have twins, that the "trials" are independent with probability 1 2 of a boy, and that they are fertile enough to keep producing children indefinitely
- Combinatorics - Arranging boys girls - Cross Validated
Six girls are to enter a dance with 10 boys to form a ring so that every girl is between two boys: (a) What is the probability that some specified boy remains between 2 boys? (b)what is a the proba
- Probability of having a sister - Cross Validated
The probabilities of having sisters are equal for girls and boys -- this was an assumption I made in the start, namely that girl and boy births are independent Some reproduction biologists may argue against this assumption, but then we would need more information than just the probabilities pk
