WebP (all female)= 1/2 x 1/2 x 1/2 = 1/8 P (all male ) = 1/2 x 1/2 x 1/2 = 1/8 P (all one gender) = P (all female) + P (all male) = 1/8 + 1/8 = 1/4 What is the probability that a three-child family is two girls and one boy? Each possible birth order has P=1/8. That is, P (G,G,B)=P (G,B,G)=P (B,G,G)=1/8. So, P (2G,1B)= 3/8 and P (1G,2B)= 3/8.
