learn.whatIsHeading

A coin flipper simulates a fair coin toss with 50% probability of heads or tails. Despite the simplicity, coin flipping is the foundation of binary decisions, probability theory, and cryptographic key generation.

分步指南

1. 1Each flip is independent — previous results do not affect future flips
2. 2P(heads) = P(tails) = 0.5 (50%) for a fair coin
3. 3Expected number of heads in n flips: n/2
4. 4The longest known streak of heads on record: 10 consecutive heads occurs on average every 1,024 flips
