In: Statistics and Probability
A married couple has 3 children. What is the probability that they have 2 boys and one girl? Note: you can assume that for each birth, p(girl) = 0.5, p(boy) = 0.5.
Given that a married couple has 3 children.
and P(Girl) = P(Boy) = 0.5
It is clearly a case of binomial distribution where n = 3
Let X be the number of boys.
Now,
