We divide all the numbers from 1 to 49 in 10 groups of 5 numbers each called pentads.
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 5 numbers except for the last group 46-49 that has 4 numbers but we will still call it a pentad. The numbers extracted are distributed into 2,3,4,5, or 6 pentads out of the total of 10 pentads. In most of the cases they are distributed in 5 pentads meaning that in a single pentad we have 2 numbers of each and in the others we have one number of each. The reduction is big!
And yet, whoever rejects the idea of having 6 winning numbers and thinks of having 5 winning numbers will distribute the numbers in 4 pentads. It’s only a hint...
The chart displays on the abscissa the combinations with pentad numbers 2, 3, 4, 5, 6, and beside each combination there is a column indicating how many times the respective combination was extracted (the number in displayed above).
