What is the probability that if a couple has 4 children that they will have 2 boys and 2 girls in any order?
2 Answers By Expert Tutors This is a Binomial Distribution Problem. There are 4C2 ways to have exactly 2 boys & 2 girls, in any order, so this gives 6/16 =3/8 as the correct probability.

The odds of having a girl or a boy are the same with a one in two chance of it being one or the other. 50/50 if you like.
What is the probability of all three children being girls?

What is the probability of having no boys in each generation?
Conversely the chance of having no boys is 1 / 2 in the first generation, 1 / 4 in the second, and 1 / 8 in the third. This generalizes to 1 / 2 n in the nth generation. (Essentially I’ve drawn a probability tree diagram here, which generalizes to much more complicated problems).
