Assuming that the births at the hospital are equally likely to be of either gender then the answer is (1/2)4 = 1/16
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, the probability that the next seven births are girls (given that the global probability of a girl is 0.48), is 0.00614 approx.
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 three out of three being girls is 0.1127.
Probability of girl, assumed to be 0.5. Therefore, probability of 5 girls is 0.5^5 or 0.03125.
If the choice is unbiased, the change is 14/(10+14). If the chooser prefers choosing boys, the probability is 0.
Assuming that the chance of a woman giving birth to a boy or a girl is the same (in reality there's about 105 boys born for every 100 girls) then the probability of 22 of the same gender births *in a row* is: P=(0.5)^22=0.0000002384 or 1 in 4,194,304 It depends on the "when" of the question. If you point at a childless woman, and say "She will give birth to 22 children. What is the likelyhood that they will all be girls?" In that case the probability will be one in two-to-the-twenty-second. Pretty long odds. BUT, if you point at a woman with twenty one children, and ask "What are the odds that the next one will be a girl?" Then the answer is one in two. Make sense?

0.48
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!

Oh, dude, the probability of the next child being a girl is still 50/50. Each birth is like a coin flip - it doesn't matter what came before. So, you could have a dozen girls in a row and the next one could still be a girl. It's all just random chance, man.
The probability is 2 - 6
the answer is no because an estimated of 107 births that are boys and 100 of girls. That is the answer to that question.
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.
The overall ratio of live births worldwide is about 1.01 births for boys to 1.0 for girls. That has been the ratio since records have been kept.
