Is a coin flip truly 50/50?

For a fair coin, yes—each flip has exactly 50% chance for heads or tails. However, physical coins have slight biases due to weight distribution. Studies show real coins land on the same side they started about 51% of the time. Digital coin flips are perfectly 50/50.

How does the gambler's fallacy apply to coin flips?

The gambler's fallacy is believing past outcomes affect future probability. After 5 heads in a row, the next flip is still 50/50—coins have no memory. The probability of 6 heads in a row is low (1.56%), but given 5 heads already occurred, the 6th flip is still 50%.

What are the odds of multiple coin flips?

Multiply probabilities: 2 heads in a row = 0.5 × 0.5 = 25%. 5 heads = 0.5⁵ = 3.125%. 10 heads = 0.5¹⁰ = 0.098% (about 1 in 1,024). Any specific sequence of N flips has probability of (1/2)^N.

When should I use a coin flip for decisions?

Coin flips work well for: breaking ties, making quick decisions between two equal options, or resolving disputes fairly. Research shows that for difficult decisions, people who follow the coin flip tend to be happier with outcomes 6 months later.

How is digital coin flip randomness generated?

Digital coin flips use computer random number generators. A random number between 0 and 1 is generated; values below 0.5 are heads, 0.5 and above are tails. Our tool uses cryptographically secure randomness for fairness.

Coin Flip

A fair coin flip has exactly 50% probability for heads and 50% for tails. Multiple flips: probability of n heads in a row is (1/2)^n. Two heads = 25%, five heads = 3.125%. Each flip is independent—past results do not affect future flips.
