You can put this solution on YOUR website! The ratio of boys to girls at birth in a country is quite high at 1.09:1
What proportion of families of that country with exactly 6 children will have at least 3 boys?
---------------------------
P(having a boy) = 1.09/(1+1.09) = 0.5215
----
Binomial Problem with n = 6
P(3<= x <=6) = 1 - P(0<= x <=2) = 1 - binomcdf(6,0.5215,2) = 0.6957
