Subject:  For attention of GNU Octave Team! I need Information about the GNU Octave tools and uses

Dear GNU Octave Team,
Good Day.
Recently I have been interested in learning to use GNU Octave , a lot because I realized a very wide range of things that this tool can help me. I saw that GNU Octave presents on your interface many statistical tools that could be useful in solving my demand. However, because I am not successful in properly targeting theese tools to my needs, I therefore kindly request specialized support regarding the uses of the tools needed to solve this demand.
It happens that I have tried using GNU Octave to make lottery bets, but even though I have an idea how to direct the use of this program tools I do not have the knowledge to put my ideas into practice.
My idea is to use some data provided by the raffle developer to try to "figure out the numbers drawn," although this information is not directly related to the numbers that are drawn. The lottery bet I want to bet on is the draw of 5 numbers from 1 to 80 that do not repeat each other in the same draw. The bettors can choose at least 5 numbers and a maximum of 15, and the higher the number of numbers chosen the higher the bet amount and the greater the probability of success of the numbers drawn. You win who hits 2, 3, 4 and all 5 numbers, of course the values will be larger according to the number of hit numbers, whoever hits all 5 numbers wins the total amount.
The data I would like to use in GNU Octave to try to figure out the numbers consists of the total collection amount from the draw, from the accumulated to the next draw, from the accumulated to the special draw (in a table) and from the probability of success (if possible 5 numbers drawn), in addition to the numbers drawn in the previous contest. Is there any form or formula I could use so that by giving random numbers to Excel base on this information?
Quantity of numbers bet  Bet price  Probability of correctness (1 in ...) If 5 correct numbers.  Probability of correctness (1 in ...) If 4 correct numbers.  Probability of correctness (1 in ...) If 3 correct numbers.  Probability of correctness (1 in ...) If 2 correct numbers. 
5  1,50  24.040.016  64.106  866  36 
6  9,00  4.006.669  21.658  445  25 
7  31,50  1.144.763  9.409  261  18 
8  84,00  429.286  4.770  168  14 
9  189,00  190.794  2.687  115  12 
10  378,00  95.396  1.635  82  9 
11  693,00  52.035  1.056  62  8 
12  1.188,00  30.354  714  48  7 
13  1.930,50  18.679  502  38  6 
14  3.003,00  12.008  364  31  5,8 
15  4.504,50  8.005  271  25  5,2 
For example:
Total Accumulated  Accumulation for the Next Draw  Accumulated for the Special Draw  Sorted Numbers  
Draw 1  7,562,295.00  7,562,295.00  101,661,983.00  9  26  29  37  48  
Draw 2  7,960,633.50  4,411,350.00  102,024,325.00  32  45  56  63  67  
Draw 3  8,853,382.50  130,000,000.00  102,427,303.00  80  80  80  80  80 
In that case, how could I use the total collection information, the accumulated value for the next draw and the accumulated value for the special draw for the previous bets, and the probability of 5 numbers drawn in a single 5numbered bet (1 / 24,040. 016) to try to find the numbers drawn from the next contest (Draw 4)?
So far I've only been able to program GNU Octave to choose random numbers individually from 1 to 80, without relating to the numbers you want. Would it be better to program GNU Octave to provide the numbers drawn in a group (in the case of 5 numbers group)? How would I do that? Is it necessary to use a combination function to find out how many combinations are possible by choosing 5 numbers in 80 numbers?
Therefore, it would be possible, if you please, to give me specialized support in the present demand, that is to say, in the elaboration of the formula, or in the provision of information for me to elaborate a formula or some other idea that may be useful to solve this problem?
P.S.:
1) Another interesting information is that the gross premium corresponds to 45.3% of the Total Accumulated. Of this value:
35% are distributed among the hitters of the 5 numbers,
19% among 4number hitters,
20% among 3number hitters,
11% between the twonumber hitters and
15% accumulate for the hitters of the 5 numbers of the Special Draw
If there is no winner in any award range, the amounts accumulate for the next contest, in the respective bands.
2) I tried to use Excel (which features many similar tools to GNU Octave), but I was not successful either. Again the lack of knowledge of the use of the tool and the formulas made the success impossible. If GNU Octave does not have sufficient resources to achieve the desired result, it is possible that you will be able to provide technical support regarding the preparation of the formula and provide other useful information for the use of this tool, please ?
3) I was not able to direct the tutorial topics present on the GNU Octave website in the search for the intended object.
Best regards,
Luis Roberto.
