You can put this solution on YOUR website! Assuming boy and girl babies are equally likely, find the probability that a family with 3 children will have exactly 2 boys?
-----------
3 kids, each with 2 genders --> 2^3 = 8 possiblities
However, that includes having 0, 1 or 2 progeny.
If there are 3:
BBB
BBG
BGG
GGG
2 boys & 1 girl is 1 in 4 probability.
