    LeoStatistic have a special tools permitting to do experimental research of probabilities of complex events. Lets do it for craps game:

    Open LeoStatistic.

    In tab "Data" click on "Insert" button. Select "From formula", name "c1" and print there : "int(1+rand(5.9999))"

    Repeat the same one more time for name "c2" and the same formula

    Next time for name "craps" enter formula" "c1+c2"

    Make states of "c1" and "c2" "Inactive" and  state for "craps" - "Value".

    In tab "View" press on button for displaying in histogram style.

    I tab "Statistics" select "Show percentage"

    Result picture has to be like this:

    Craps probability

     If to do a small job to get from result panel numerical data: copy, paste into MS Excel, create table and so on you can produce a table of probabilities of any number in Craps game:

    Sum of craps Probability, (%)
    2 3.1
    3 5.8
    4 8.8
    5 11.3
    6 13.2
    7 16
    8 14.4
    9 10.2
    10 8.1
    11 6.4
    12 2.7

    Probability to win at first draw, to get 7 or 11, is 22.4%. To lose at once with 2, 3, or 12 - 10.6%. Full analyze of the the game is not a subject of this sample and quite difficult but in general you get a picture.
