With no other factors known, the chances are almost the same for a boy or girl (very slightly more boys are born). So, the chance would be approximately 33% that you would get two girls, and 33% that you would get a girl and a boy. 66% that there would be a girl at all (either girl-girl twins or girl-boy twins).
I suppose you mean, the couple already has 2 girls. In this case, the odds are about 50%. If the couple already has 6 boys and no girls, the odds are about 50%. If the couple has a boy and a girl, the odds are about 50. If the couple doesn't have children yet, the odds are about 50%.
Check it out on the internet. There are certain positions of sex that tend to result in girls. The acidity or alkalinity of the birth canal makes a difference. None of these is foolproof, but you can push the odds quite a lot toward a girl. (Or boy)
Not very big. More then 1000 girls have tried but none have succeeded...yet!
Church has the best odds but that is not a guarantee. Understand that a real "pure" girl will stay that way until marriage.
The odds of having sextuplets are 1 in 3,939,040,643.
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?

Please explain what is "a 400 girl"
hey girl hey girl hey girl
Because you can only double down on your first action, the odds of getting a face card are 4/48 or 1/12
The odds of rolling any double number is 1:36
The odds are definitly against. The world would be without humans in only a generation or two if everybody got their girls pregnant that way. I would say you are pretty safe.
