Birth months are not uniformly distributed across the year. However, if yo assume that they are, the probability is 0.9536 (approx).
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
the probability is very small
2/6 is not accurate. using a theoretical method for equally likely outcomes, there are 2 possible outcomes for each birth: either a boy(B), or a girl (G). For a family of three children, the total number of possibilities (birth orders) is 2*2*2=8 to double check this work, here are the eight possible outcomes:BBB, BBG, BGG, GBB, GBG, GGB, and GGG. You want EXACTLY two girls, this assumes that the other must be a boy. Therefore, the probability that a three child family has 2 girls one boy is P(2 girls)=3/8=0.375
Probability of girl, assumed to be 0.5. Therefore, probability of 5 girls is 0.5^5 or 0.03125.
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 third child is a girl is the same as the probability that any birth is a girl - which is 0.48 across the world.

If you assume that birth dates are uniformly distributed over the year (they are not), and you ignore leap years, then the probability of two people selected at random, share a birthday is 1/365.

about 1/300, but it also depends on age and family history
If you mean your birth family as opposed to your wife and minor children , the wife and children are your primary responsibility .To help birth family members they can be helped, but you and your wife nust agree to what extent.
The most children in one family record belongs to the Feodor Vasilyevich family. The mother gave birth to 69 children in her lifetime during the 1700s.
the probability is very small
Not much is known about his birth. The record exists of his christening, on April 26th, and most children in Stratford in that period were christened three days after their birth; so it is reasonable to assume that Shakespeare's birth was on the 23rd, but there is no proof of it.
The NHS Birth to Five Years book states that pate must not be given to children under the age of 1. Therefore assume that it is fine for children above this age.
Family planning allows a couple to plan the number of children, the time between births, and offers birth control options.
