About Coin Flipping

Flipping a coin is a common way to make a simple, random decision between two choices. In a fair flip, a coin has an equal probability of landing on either "heads" or "tails" (a 50/50 chance).

Heads or Tails?

The two sides of a coin are named "heads" and "tails." "Heads" typically refers to the side that features a portrait of a person, while "tails" is the opposite side. This tradition dates back to Roman coins, which often had the head of an emperor on one side.

Probability

While a single flip is unpredictable, the law of large numbers states that as you flip a coin more and more times, the ratio of heads to tails will get closer and closer to 1:1. However, short sequences of flips can often appear skewed (e.g., getting heads five times in a row is statistically possible).
