The 2-dice game is a simple example of pre-calculated or a-priori chance.
How it is played: Mr.Patent and Mrs.Loto each bet any number between 2 and 12,
then toss two dice: the winner
will be the one whose chosen number matches the outcoming tossed number.
Suppose Mr.Patent bet on number 12 and Mrs.Loto on number 9: who has the best chance to win ?
Mrs.Loto has exactly 4 times winning chance than Mr.Patent.
In fact the number chosen by Mrs.Loto may come out in 4 different ways:
1) Die A = 3 , die B = 6
2) Die A = 4 , die B = 5
3) Die A = 5 , die B = 4
4) Die A = 6 , die B = 3
whereas the number chosen by Mr.Patent has only one possibility:
1) Die A = 6 , die B = 6
This great difference in matching chance reminds the example illustrated in our
Benchmark page where our system shows an optimized lotto chance 4 times better than
those of other professional systems.
What happens now if the dice players decide to keep on tossing for a whole evening ?
At the end of the evening the number 9
staken by Mrs.Loto shall have outcome around 4 times more frequently than the number 12,
confirming the winning odds of 4 to 1, as predicted by theory.
This reminds the 4 to 1 ratio to achieve the same lotto chance to match at least 3 numbers
when playing the 31 number abbreviated wheel illustrated in our benchmark page,
requiring 4 to 1 lower expense for the same matching power offered by one of the best optimized lotto
systems on the web !
