## The Probability of Dice Throws in Craps

For example you have tossed the dice around thirty-six times. According to existing rules of probability, you can expect to receive 6 sevens, 5 sixes, 5 eights, 4 fives and 4 nines, 3 fours and 3 tens, 2 threes and 2 elevens and 1 two and 1 twelve. Payout for the various wagers and aspect of the game like the casino advantage, are based on the prediction that what you will expect in the game is what will be given to you. But in reality, it does not work that way.

That is the reason why in some casino visit despite the time duration, some good players win a lot of money while others lose every penny that is in their pocket. One of the main reasons for this situation is that expectations are not that solid. If you tossed the dice around thirty-six times, you may get 6 sevens, 5 sixes, 4 fives and others. But you might be unfortunate to see none, even a thirty-six or any other digit. The probability of possessing 6 sevens is 17.6%. The 82.4% that is remaining is the probability of getting some other digit.

A good way to ponder about this is think about 1,000 crapshooter tossing the dice thirty-six times each. If these percentages will be followed for one thousand times, only one hundred seventy-six crapshooters would get 6 sevens. The other eight hundred twenty-four crapshooters would receive a smaller amount or more. Like on the down side, one hundred seventy crapshooters would get 5 sevens, one hundred thirty-three, eighty 3 on the upper side, one hundred fifty-one would get 7, one hundred nine 8 and 68 crapshooters would get nine.

So why do mathematically gifted individuals tell you that you should expect 6 when they really know that you have a small chance of getting it? 1st, 6 sevens is the overall average recorded over lots of crapshooter. 2nd, it will be likely result, as can be seen from the drop on the total figures above and below 6 sevens. The overall effect is the same for all digits.

The probability of eight five 6's or 8's is around 18.9%. That of four 5's or 9's is 20.7%. Three 4's or 10's have probabilities of 23.4%. Two 3's and 11's have a probability of 27.8% and one 2's or 12's have a probability of 37.3%. What will happen when you increased the number of trials? Like three hundred sixty dice throws, when the expected total number of 7's is sixty? Player intuition might dictate that the rule of large digits would increase the probability that you will get your assumed average. This turns out not to be the issue. The probability of 60 7's in three hundred sixty dice throws is 5.634%, less than 17.6% of six 7's in thirty-six dice throws. But sixty is the total average and will be likely the overall result with 5.634% greater than the odds of any other 7's.
