I'm delighted to know the information below was a satisfactory
answer to your question.
From lottery questions and answers:
"Q: Are there any statistics regarding which picking techniques are winners?
Do quick-picks win more often than hand-picked numbers?
A: The percentage of quick-picks varies a great deal from game to game
and also with the size of the jackpot. In Powerball, the quick-pick
percentage normally runs about 70 percent, and about 70 percent of the
winners are quick-pick players.
The bottom line is that how you pick your numbers has absolutely
nothing to do with being a winner. The numbers 1-2-3-4-5*6 have
exactly the same chance of winning as any other set of six numbers.
The only thing is, if you pick your own numbers, and you base them on
something logical, artificial or limiting (like dates), you are more
likely to have to split the pari-mutuel jackpot prize because others
may be using the same numbers. The most commonly played number
combination is 7-14-21-28-35*42. If you won with that number, you
would share the jackpot with many, many other players."
