What is a Lottery Draw?
A draw is the event where winning lottery numbers are randomly selected from a pool. Each draw is an independent event — previous results have zero influence on future outcomes.
How Draws Work
Most major lotteries use one of two methods:
- Mechanical ball machines — numbered balls are mixed and drawn physically
- Random number generators (RNG) — computer-generated random selections
Draw Independence
This is the most important concept in lottery mathematics: each draw is completely independent. The fact that number 7 hasn't appeared in 20 draws doesn't make it "due." The probability remains exactly the same every single draw.
