Blackjack

My dealer dealt an 11 card 21 to himself with an 8 deck shoe. Only way is 222222AAAA5. Anyone know the odds of this happening?

That has to be a party trick, if it happened. Without calculating the probability, I'd say kin' Massive!



OK. Let's have a stab...

(32/416)*(31/415)*(30/414)*(29/413)*(28/412)*(27/411)*(32/410)*(31/409)*(30/408)*(29/407)*(32/406).



1 in 3,136,064,636,921 approx



It didn't happen fairly. No way!

That's what I was thinking. That's unbelievable odds. Thanks for doing the math

My maths is a bit squiffy, because other cards would also have been dealt. But it's close enough to say no way it happened without sleight of hand.
