in thread Fastest way to calculate hypergeometric distribution probabilities (i.e. BIG factorials)?

*BTW, do you really mean "the odds"? Or do you want the probability p? [...] (The odds are (1– p)/p.)*

Hmm, if the probability is 25%, I'd read that as implying "the odds are 3". But that isn't right: the odds are "3 to 1 against", which means the same as 25% - in fact I'd consider it reasonable even to say "the odds are 25%".

I'm not sure if there is a name for what *(1-p)/p* represents, but I don't think "the odds" is it.
