Hey guys.
I'm looking for a recommendation on a good probabilities website.
Thing is, recently I was working on hand distributions, and I said something like:
A pair is 4*3/2 = 6 hands
Overs (AK) is 4*4/2 = 8 hands.
This isn't true.
Basically, because the overs are created of 4 unique aces, each with a set of 4 unique kings: there's no overlaps, and therefore we have 16 hands rather than 8 hands.
Also, the pairs isn't really 4*3/2, but rather, 4*3/2!, which is equivalent...
Where I would run into trouble using the /2 rather than /2! is if I were trying to figure out the chances for flopping a monotone flop, which would involve something like /3!, rather than a potential mistake: /3
(the difference between 3*2*1 (=6) and 3.)
----------
Anyways, I'm kinda embarassed at my amateur mistake, and would like to check out a beginner's probability website, that would cover this material. If anyone has any suggestions, please let me know!
