The data is as of May 14 2019.
It rarely happens that the numbers (I am talking about the first 5 not the megaball or powerball itself) are all numbers from one category. For example, last drawing of the Powerball, one number was from the picked once caegory, one from the picked more than once and 3 from the never picked. In the case of the MegaMillion 3 where picked from those numbers that were picked once, 1 from those picked more than once and 1 from those never picked.
If you are picking numbers this can be helpful, because you can make sure to pick from different categories and also given that rarely are all numbers odd or even it can help you further.
