GameTek Classic 271.5 - Hypergeometric
Ludology - A podcast by Erica Hayes-Bouyouris, Sen-Foong Lim - Sundays
Geoff runs us through the Hypergeometric and Binomial functions in a spreadsheet application like Microsoft Excel. Don't be intimidated by their names; they're actually pretty easy to use, and invaluable for game designers. You can find Geoff's GameTek newsletter on this subject here.
