>>> Calculating Dice Odds at the
Craps Table All craps players need to know
the odds of rolling the dice. In order to fully
understand how good your chances are at winning, it is
essential for you to understand just how often each dice
roll shows up on the table. The reason the game is
centered around the number 7 is simply because this
number is rolled more than any other number. You
better believe the casino has calculated the odds for
every single roll of the dice, and knows how and what
their advantage over the player is for every bet.
As you know, a die has six sides with six different
values, and that two die are rolled every time. A
good guess would be that since there are six different
numbers on two die's then there would be twelve
different possible outcomes of the roll. However,
a closer look reveals there are thirty-six different
possible outcomes of the dice roll. Since there are two
die, the same number can be rolled in many different
ways. Just like calculating the odds of playing a
lottery, all different number combinations must be
considered.
The way to go about calculating these various
combinations is by starting at the low end of possible
rolls. The lowest number on the dice is one.
If both die were rolled as one's (snake eyes) the
outcome would be 2. This is one possible roll.
The next number up is a three. To determine how
many times this can be rolled, do some simple math.
There is only one equation that will produce this
outcome: 2 + 1 = 3. Therefore, there are two
different possible outcomes:
Die One = 1, Die Two = 2 Or Die
One = 2, Die Two = 1
To further explain, let's use the number seven as a
possible outcome. Simple math reveals the sum of 7
can be produced in three ways: 1 + 6, 2 + 5 and 3 + 4.
Going one step further, to calculate the number of times
these outcomes can be rolled, simply multiply the
outcome by 2 (representing two die) and you have the
value of six - There are six ways to roll the number 7
with two die. The combinations are shown here:
Die One = 1, Die Two = 6 Or Die
One = 2, Die Two = 5 Or Die One = 3, Die
Two = 4
Die One = 6, Die Two = 1 Or Die
One = 5, Die Two = 2 Or Die One = 4, Die
Two = 3
If we were to do the same for each roll outcome, we
would see that the possible ways of rolling a 6 are the
same as rolling an 8. Likewise, a 5 and 9 have
equal chance of being rolled, as do a 4 and 10, 3 and 11
and 2 and 12.
Knowing this is important, for it will keep you in
the know regarding what your payoffs may during any
given wager. Remember, just because your winning
bet depends on your point being rolled before a seven,
does not mean those odds are the same for every point.
Knowing this may just play a part if you have a choice
of increasing your stake on a wager. To calculate
the percentage of you chances at rolling a certain
number, divide the number of possible outcomes by the
number of total dice outcomes (36). For the number
7, this would show as 6/36 x 100% = 16.6%
