About Coin Flipping

Flipping a coin is a classic way to make a simple random choice between two options, commonly represented as "Heads" or "Tails." In theory, a fair coin has an equal probability (50%) of landing on either side.

How to Use the Simulator

1. Number of Flips: Enter how many times you want to simulate flipping the coin.
2. Click the "Flip Coin(s)" button.

Interpreting Your Results

• The results of each individual flip (Heads or Tails) will be displayed.
• If you performed multiple flips, a summary will show the total count and percentage for both Heads and Tails.

Randomness and Probability

While a fair coin has a 50/50 chance for each outcome on any single flip, the results of a small number of flips might not reflect this perfectly. For example, flipping a coin 10 times might easily result in 7 heads and 3 tails.

However, according to the Law of Large Numbers, as you increase the number of flips significantly (e.g., thousands or millions), the overall percentage of heads and tails will tend to get closer and closer to the theoretical 50% probability.

This simulator uses a pseudo-random number generator (PRNG) provided by your browser's JavaScript engine (Math.random()) to simulate the randomness of a coin flip.

Uses of Coin Flips

• Making simple binary decisions.
• Starting games (e.g., determining which team goes first).
• Randomly assigning participants to groups in experiments.
• Illustrating basic probability concepts.

Limitations

• Uses a pseudo-random number generator, not true physical randomness.
• Assumes a perfectly fair "coin" with exactly a 50% chance for Heads or Tails. Real coins might have slight imperfections.
