Odds of being dealt AA

[rminusq]

Man, getting dealt quad aces at an Omaha table has to be such a shame. What a waste of beautiful cards.

Couple more if you care.

AAWX (W is 2-5; X is any card)
c(4,2)*c(16,1)*c(49,1)/c(52,4) =0.01737

A2XX
c(4,1)*c(4,1)*c(50,2)/c(52,4)=0.072398

To back out the AA2 combinations from the 2 above, subtract
c(4,2)*c(4,1)*c(49,1)/c(52,4)=0.004344

Combined chance of AAwx or A2xx=0.08543

So about every 11 hands you should either see AAwx or A2xx. This doesn't track suits.

In a recent SNG I was dealt four AAxx hands in a row. I see that's none too likely!
