PROBABILITY
If among (F+U) equi-probable and mutually exclusive
events, F is regarded as favorable and U as
unfavorable, then for a single event, the probability of
a favorable outcome is:
The probability of an unfavorable outcome is 1 minus
the probability of a favorable outcome.
In other
words, since there is the same chance that any
number may win on any spin (mutually exclusive
events), the chances of winning equals the number
of winning numbers divided by the total number of
possible numbers.
Roulette has 38 possible
numbers that may win. Therefore, F+U is always
equal to 38. If you wager on a single number, the
chances of winning are 1 divided by 38, or
approximately 97.37%. If you win, the house pays
you 36 times your wager. Multiplying your chance of
winning times your payback shows the advantage for
the house. In this case, the number is 94.74% which
means the house has a 5.26% advantage over the
players wagering on a single number.
If a wager is placed on black or red, the probability of
winning is 18 divided by 38 because the number of
black numbers and the number of red numbers is 18.
The probability of a favorable outcome is one color is
wagered equals 47.4%. The payout if you win is 2 to
1. This yields an advantage for the house of 1 -
(0.474 x 2) or approximately 5.26%. As you can see,
the house always has a 5.3% advantage.
