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:

 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.
