Coin Flip Simulator
Flip a virtual coin and track heads/tails statistics over multiple flips.
What Is the Coin Flip Simulator?
A fair coin has equal probability of heads and tails (50/50). This simulator flips virtual coins and tracks the running statistics, demonstrating the law of large numbers.
Formula
How to Use
Click Flip Once to flip a single coin. Click Flip 10 or Flip 100 to batch flip. The statistics panel shows total flips, heads count, tails count, and percentages.
Example Calculation
Click Flip 100 several times and observe how the heads percentage converges toward 50% — this is the law of large numbers in action.

Frequently Asked Questions
Is it truly 50/50?
Yes, each flip uses Math.random() < 0.5 which gives equal probability to heads and tails.
Why doesn"t it land exactly 50/50?
Random variation is normal. With small samples you expect deviation. The more flips, the closer to 50%.
What is the longest streak shown?
The simulator tracks and displays the current streak of consecutive heads or tails.
