How does the streak tracking work?

The simulator tracks consecutive heads or tails results, showing you the longest streak for each outcome in your session. Great for observing probability in action.

Can I flip more than 10 coins?

Yes! Adjust the number of flips from 1 to 1000 to experiment with probability and see how results converge toward 50/50 over many flips.

Why track coin flip statistics?

Statistics help demonstrate the law of large numbers - over many flips, results approach 50/50. Useful for teaching probability and validating randomness.

What's the longest possible streak?

There's no theoretical limit - you could get heads 100 times in a row, though the probability is extremely low (about 1 in 1,267,650,600,228,229,401,496,703,205,376).

Can I reset the statistics?

Each session tracks flips independently. Refresh the page or clear results to start a new statistics session.

Is this useful for classroom teaching?

Yes! Teachers use this to demonstrate probability, the law of large numbers, and statistical concepts with visual, real-time results.
