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 of the next child being a girl after six girls have already been born is 0.5 or 50%. This is because the gender of each child is independent of the gender of the previous children, and the probability of having a girl is always 0.5 for each birth. Therefore, the probability remains the same regardless of the gender of the previous children.
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. Unfortunately there is no readily available research into the genders of seven or more children to establish the experimental probability for such an outcome.
However, if you assume that they are independent events then, given that the probability of a girl is approx 0.48, then the probability of the seventh child being a girl is 0.48.
50% then 25%
In most industrialized countries there are about 105 boys born for every 100 girls. This number does change so it is NOT constant, but it gives you a rough idea. so 105+100=205 AND 105/205 =.512195 which is the probability of being born male.
if we assume that the probability for a girl being born is the same as a boy being born: (1/2)^6 = 0.015625 = 1.5625%

However, if you assume that they are independent events then, given that the probability of a boy is approx 0.5169, the probability of the event described is 0.5169*1*1*0.4831 = 0.2497

The chance that their eighth child will be a daughter is 50%. The gender of a child is independent of the genders of their siblings, so each child has an equal probability of being a girl.
The child will have the disorder, only if the recessive allele from both the parents is transferred to the child. Therefore, the probability is 1/4.
1 in 2 children born will be male.
According to the American CIA, worldwide the number of boys born to the number of girls is 1.07:1, which implies a probability of about 0.517. This varies somewhat by country, for instance. At one extreme, according to the list of countries by sex ratio presented in wikipedia is Liechtenstein at 0.558, at the other Haiti at 0.503.

The probability of a colorblind child being born is 50%. This is because the male passes his Y chromosome to all his sons, and since he is colorblind, his sons will inherit the colorblind gene from him. The daughters will inherit their X chromosome from the mother and have a 50% chance of being carriers like her.

The change occurred because the probability of having a boy is always 50/50 each time a child is born, regardless of the gender of previous children. Having four girls has no impact on the gender of the fifth child.
The probability of two people's birthday being the same is actually more likely than many would think. The key thing is to note that it doesn't matter what the first person's birthday is. All we need to work out is the probability that the second person has a birthday on any specific day. This probability is 1/365.25 The probability that they were born on June 10th is 1/365.25. The probability that they were born on February 2nd is 1/365.25 and the probability that they were born on the same day as you is 1/365.25
