Dynamic Probability Insights
How Coin Flipping Works
Two outcomes
A coin flip has two possible outcomes.
Fair chance
A fair coin gives each side a 50% chance.
Independent flips
Each flip starts fresh.
Counts
Multiple flips can be counted and summarized.
Percentages
Percentages show how results compare over time.
Fair Coin Probability Explained
Heads probability
Heads has a 1 out of 2 chance, or 50%.
Tails probability
Tails has a 1 out of 2 chance, or 50%.
Small samples
10 flips may not split exactly 5 and 5.
Large samples
More flips often move observed percentages closer to 50/50.
Fresh flips
Independence means each flip does not remember the last flip.
Expected result
The expected split is 50/50 over many flips, not every small batch.
Randomness, Streaks, and Probability Notes
Streaks happen
Five heads in a row can happen naturally.
Not due
A previous heads result does not make tails guaranteed next.
Short histories
Small samples can look unbalanced.
Browser logic
Virtual flips are generated by browser random logic.
