What is the probability that all of the children will be girls?

First, since the chance of a child being a girl is 1/2, the chance of all three being girls is (1/2) (1/2) (1/2) = 1/8. Alternatively, make a list of all possible outcomes, in order of age: {GGG,GGB,GBG,BGG,GBB,BGB,BBG,BBB}. As each one is equally likely, the chance of GGG is again 1/8.
