As mentioned earlier.
Craps is a dice game played with two regulation dice. There are 36 possible combinations. The key number in craps is seven. The entire game revolves around rolling or not rolling a seven. Learn to hate seven's. They are the scourge of the game.

Ways To Roll
The game begins to get a little clearer once the math and odds at which the game is played is explained.
The Seven has six possible ways to come up. Yet, there are thirty ways other numbers can come up, so the odds, in general, are very good that a number other than a seven will come up; but remember that the chances of rolling 7 are one in six.
The way combinations work is that in 36 rolls, each combination should come up once. It does not! Never has. And the probability that it will happen is there, but how long does anyone have in thier life to prove such a theory? Plus it never worked for flipping a coin either.
The flaw in those rolling, continuous combination theories is that the COIN or the DICE do not remember what they landed on last time.
So each flip of the coin, each roll of the dice is a brand new roll and the odds and possibilities start from scratch. There is NO continuous possibilities in anything in life. EVEN IRON BYRON, the golf swing machine, does not land the ball in the same spot every time. Wind, ball, maintenance, and so forth. There is no guarantee that it will be fifty fifty no matter how many times you flip a coin.
Bottom line: Each roll is its own separate roll. It is NOT connected to any roll previous or following. EVER! Math is absolute. LIFE is not!
Now that I have explained that, we can now understand the probabilities, the chances, the odds of rolling any number. The Dice Combination table above happens on every roll. LEARN IT, MEMORIZE IT, KNOW IT!
