We divide all the numbers from 1 to 49 into 16 groups of 3 numbers each called triads:
1, 2, 3;
4, 5, 6;
7, 8, 9;
10, 11, 12;
13, 14, 15;
16, 17, 18;
19, 20, 21;
22, 23, 24;
25, 26, 27;
28, 29, 30;
31, 32, 33;
34, 35, 36;
37, 38, 39;
40, 41, 42;
43, 44, 45;
46, 47, 48, 49.
Each group has 3 numbers, except for the last group that has 4 numbers. We will still call it a triad.
The numbers extracted are distributed into 2, 3, 4, 5 or 6 triads.
If you look at the statistics, you will notice that it is a very high probability for the numbers to be distributed in 5 or 6 triads.
We would select 5 triads to increase our chances of getting 5 numbers.
The chart displays the combinations with the number of triads 2, 3, 4, 5, or 6 on the abscissa and there is a column showing how many times the respective combination was extracted next to each combination (the number is displayed above the column).
