Assuming boys are equally as likely as girls, 125 boys would be expected.
The probability of getting 140 or fewer boys is approximately 97.51%
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
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%
In a family with four children, the probability of having four boys is 1 in 16.
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 the choice is unbiased, the change is 14/(10+14). If the chooser prefers choosing boys, the probability is 0.
2 babies are born in April.
Babies are born.
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 boy is approx 0.52, the required probability is 0.3126.

If everyone had penasis, then no babies would be born.

what do u mean ... boys have babies too Because then, where does it come out?
Girls have babies and boys don't have babies because of the organs in their bodies. Boys do not have the organs (the womb) to grow the baby within their bodies.
Fewer and fewer boys from poor backgrounds were let into the knighthood.
