Assuming all sex distributions to be equally probable, what proportion of families with exactly six children should be expected to have three boys and three girls?
----
# of 6-child families with 3 boys = 6C3 = 20
---
# of different boy-girl family patterns: 2^6 = 64
-------
Proportion: 20/64 = 5/16
