The core mathematical idea
Lottery games are combination problems. The exact odds depend on the game rules: pool sizes, how many numbers are selected, bonus balls and prize conditions. A strategy can alter how many combinations you cover; that is different from predicting the drawn combination.
Cost matters
More tickets can cover more distinct combinations, but every additional ticket costs money. Compare increased coverage with increased spend rather than discussing coverage in isolation.
Important: Lottery play involves risk of loss. Historical analysis does not guarantee future results. Verify game rules and product terms where you live.
