(assuming that the probability of having a girl or a boy is 50/50) Looking from beforehand, the probability of having three boys then a girl is the probability of each of these events happening multiplied together. That is 50% x 50% x 50% x 50% or 0.54 This would mean that the chance of having a girl after three boys is 0.0625. If you've already had the three boys though, it is a different story. The point is that previous experiences do not affect future ones; probability has no memory. Thus the probability of having a girl next is 50%, regardless of if you've had boys or girls in the past. To think otherwise is known as the gambler's fallacy, where a gambler says "black has come up 4 times in a row, it must be red next" even though the chance of red is always 50%
This question is extremely poorly phrased. The probability of three boys [sitting] in a row at an all boys school is 1. At an all girls school it is 0 and is otherwise somewhere in between. If the question is about birth order, do you take account of the fact that nearly half the families have two or fewer children? So that in half the cases the probability is 0. Finally, 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 boy is approx 0.52, the probability of giving birth to three boys in a row is 0.523 = 0.1381
you have about a 42% chance for that to happen
Assuming that the probability of having a baby girl is 1/2 and that of having a baby boy is 1/2, the probability of having 3 baby girls in a row is (1/2)(1/2)(1/2)=1/8.
The chance is 3.5/7.
Each time they have a child, there is a 50% chance it will be female.Therefore the chance of getting three daughters in a row is 12.5% (0.5 X 0.5 X 0.5 = 0.125).
you have a 75% chance
Every time 2 people mate to produce an offspring, there is a 50/50 chance it will either be a boy or a girl. This can be explained using a Punnet Square. XX is a girl and XY is a boy. XX XY XX XY XX XY The chance of a mom having one girl is 50? or 1/2 The chance of her having a second girl is 1 in 4, or 25% The chance of her having 3 girls is 1 in 8, or 12.5% The chance of her having 4 girls in a row is 1 in 16, or 6.25% It is unlikely, but certainly possible.
The probability of having a boy or a girl is always 50/50 each time, regardless of previous outcomes. So the theoretical probability of having a girl after having three boys in a row is still 50%.
Just about 50/50. The sex of earlier children has no bearing on the sex of the next child to be born. Each pregnancy has a (just about) even chance of being a boy or a girl.

It depends on the context. In a girls' school, it is pretty close to 1 whereas in a boys' school it will be 0.
Each chance of a having a girl is 50% or 1/2. Three different children are separate events and so multiplying the chance all three together gives 1/2 x 1/2 x 1/2= 1/8. 1 in 8 chances will someone have three girls in a row.
It's quite important because then there is a higher chance of being on a roll and having many shots in a row in.
"The same as getting heads the first time, a one-in-two chance." No It's Not! "One in two chance" means 50/50 chance. The odds of getting 2 in a row are not 50/50. I don't know what it is because that's how I arrived at this question. But if my friend were to bet me that he could get to heads in a row.... I'd take him up on that bet everytime, saying that he couldn't. He'd win a couple times here and there but in the end would lose money. It's not 50/50.
Row Mansion is right next to the lady with the dog, the gardener, the couple, and the other person.
The largest number of kids that can be in each row while maintaining the same number of boys and girls in each row would be 6. This would result in 4 rows with 6 girls and 3 boys each.
