Chess Problem

A few years back, I came across a document from the 1970s which stated that there were around 7 billion forced mate-in-2 problems (i.e. compositions) possible in chess. It never explained how they arrived at that figure. I was wondering if anyone knew.

Additionally, could the same method be used to approximate the number of forced mate-in-3 problems in the game?
