Tested lever by lever, "pick 3 lottery odds" comes down to a few levers. A player who wants better lottery odds has only a few real levers: how many tickets to buy, which game to play and how to choose the numbers. Two of those change something and one changes nothing at all. Sorting the levers that move the odds from the habits that only feel like control saves money, and it shows what a ticket actually buys ahead of the draw.
Do lottery odds increase with more tickets? Yes, in exact proportion. Each ticket with a different combination adds one more chance against the full count, so twenty tickets give twenty chances where one ticket gave one. The cost rises in the same proportion, and the expected return per ticket stays the same, which is why more tickets increase the odds without making a ticket a better buy. Buying the same combination twice adds nothing.
Odds of winning lottery quick pick tickets and tickets with own numbers are exactly the same. The machine picks a random combination and a player picks a chosen one, and the draw treats every combination alike. Chosen numbers differ in one way only: birthdays and patterns are popular, so a winning ticket built from them is more likely to share its prize. Random numbers spread a ticket away from the crowd and nothing more.
No. Balls carry no memory of earlier results, so hot and cold lists, gaps and past draws predict no better than plain guessing.
No. The draw treats every combination alike, so random quick pick lines and numbers a player chooses have exactly the same odds.
No. The cost rises in the same proportion as the chances, so the expected return per ticket stays unchanged however many are bought.
Yes, in exact proportion: twenty tickets with different combinations give twenty chances, while buying the same combination twice adds nothing.
The pool alone sets jackpot odds, so a record rollover is just as hard to hit; the only change is more players and a greater chance of splitting the prize.
