Winning Powerball Numbers show Patterns

As you can see from the Powerball winning numbers from August 28, 2013 to September 11, 2013,
1) the number 2 came up for three drawings in a row in a  7 day period.
2) the number 19 came up for two drawings in a row in a  4 day period.
3) the number 7 came up for two drawings in a row in a  3 day period.
4) the number 45 came up for two drawings in a row in a  3 day period.
5) the number 26 came up  for two drawings in a row in  a 3 day period.
6) the numbers 2, 26, and 45 came up for back to back on both September 4, 2013 and September 7, 2013.

There are other patterns thsat I have not mentioned. Is there a story here besides the balls are not getting mixed up?

When it comes to the Pick3 drawings, I can see how only 10 balls per slot can duplicate more often.

January 31, 2014 evening numbers were the same as the February 1, 2014 day numbers except in a different order.  Regular Pick3 players probably count on numbers to duplicate day to day.

Also, between February 27, 2014 and February 28, 2014, The Pick3 winning numbers were 283, 289, 281.

Lottery patterns are never consistent.
