By pairs, we mean a drawing sequence that contains at least 2 numbers in a row: 1-2, 2-3, ... 55-56.
And if you study drawing results, you will notice that these type of numbers patterns occur very often. In fact, during the past 26 Powerball and Mega Millions drawings, we find this happened 10 times in each lottery. This equals or 38.5% of the time.
However, when we calculate the combinatorial number of occurrences, we learn that there are:
- 1,364,200 paired combinations in Mega Millions (35.7% of the population), and
- 1,697,080 paired combinations in Powerball (33.9% of the population)
