Probability:

"Gender of Children: Constructing Sample Space: This section included a table summarizing the gender outcomes for a couple planning to have three children.
a) Construct a similar table for a couple planning to have four children.
2) Assuming that the outcomes listed in part (a) are equally likely, find the probability of getting exactly two girls and two boys.
3) Find the probability that the four children are all boys.

I can't find how to build such a table (I don't have a copy of the textbook), although I can guess the probabilities in terms of fractions. Still...
