🎲 Why Lottery Odds Don't Change

Interactive demonstration proving past results have zero effect on future draws

🧠 The Core Concept: Independence

Every lottery draw is an independent event. This means:

  • Past draws have zero influence on future draws
  • Numbers don't "remember" they were drawn recently
  • Numbers don't become "due" after not appearing
  • Each draw has the exact same probability: 1 in 292,201,338 (Powerball)

🎯 Interactive Demo

Pick any number between 1 and 69. Watch how the probability stays the same, no matter what happened before.

🚫 Common Misconceptions

❌ "Number 7 hasn't appeared in 20 draws — it's due!"

Wrong. The balls don't know or care what happened in the past 20 draws. Number 7 has the exact same 7.2% chance as always.

❌ "Number 42 appeared twice this week — it's hot!"

Wrong. Past appearances don't make a number more or less likely in future draws. Number 42 still has a 7.2% chance on the next draw.

❌ "If I keep playing 1-2-3-4-5, it'll eventually hit"

Technically true, but... 1-2-3-4-5 has the same probability as any other combination: 1 in 292 million. Playing it repeatedly doesn't improve your odds for any specific draw.

🎓 Why This Matters

Understanding independence protects you from the gambler's fallacy — the false belief that past events influence future probability in random, independent systems.

Real-world impact:

  • You won't waste money chasing "due" numbers
  • You won't avoid "hot" numbers thinking they're used up
  • You'll make informed decisions based on actual math
  • You'll recognize systems or strategies claiming to predict draws as scams

📐 The Math

For Powerball white balls (choose 5 from 69):

P(specific number appears) = 5/69 ≈ 0.0725 (7.2%)

This probability is constant for every single draw, regardless of:

  • Whether the number appeared in the previous draw
  • Whether the number appeared 10 times in a row
  • Whether the number hasn't appeared in 100 draws

Each draw is a fresh, independent event with no memory of the past.
