The Random Process and Gambling Theory 19
Whenit comes to casinogambling, though, the only time you can find a
positive expectancy situationisif you keep track of the cardsin blackjack,
and then onlyif you are a verygood player, and onlyif you bet your money
correctly.There are manygood blackjack books available, so we won’t
delve any furtherinto blackjack here.
Baccarat
If you want togamble at a casino but do not want to learn to play blackjack
correctly, then baccarat has the smallest negative expectancy of any other
casinogame.In other words, you’ll lose your money at a slower rate.Here
are the probabilitiesin baccarat:
Banker wins 45.842% of the time.
Player wins 44.683% of the time.
Atie occurs 9.547% of the time.
Since a tieis treated as a pushin baccarat (no money changes hands, the
net effectis the same asif the hand were never played) the probabilities,
when ties are eliminated become:
Banker wins 50.68% of the time.
Player wins 49.32% of the time.
Now let’s look at the mathematical expectations.For the player side:
ME=(. 4932 ∗1)+((1−.4932)∗(−1))
=(. 4932 ∗1)+(. 5068 ∗(−1))
=. 4932 −. 5068
=−. 0136
In other words, the house advantage over the playeris1.36%.
Now for the banker side, bearinginmind that the banker sideis
charged a 5% commission on wins only, the mathematical expectationis:
ME=(. 5068 ∗.95)+((1−.5068)∗(−1))
=(. 5068 ∗.95)+(. 4932 ∗(−1))
=. 48146 −. 4932
=−. 01174
