I'm relatively new at counting and have a mathematical/theoretical question:
The books I've read discuss an expectation of roughly 0.50% depending on the exact game (multideck, DAS, h17 or s17). To me, this mean that, on average, one would win 50 cents for every $100 bet. Over time, if one bet even $100,000, the average winnings would be only $500 - obviously meager winnings.
Apparently, I don't understand the meaning of "expectation".
Please help...
