Best of three
Each flip is independent: three heads in a row is uncommon but not broken. If you need a 50/50 once, one flip is enough. Use a tally when you are demonstrating probability, not when you are just choosing a restaurant.
When to use Coin Flip
Binary decisions sometimes deserve a coin. A virtual flip is fast, fair, and does not require digging for spare change — useful when two options are equally fine and you just need momentum. Each flip is independent, so you can also demonstrate basic probability without physical props.
Common use cases
- Decide who kicks off in a casual backyard game.
- Break a tie between two dinner options after a long day.
- Teach probability with repeated flips and a simple tally.
- Choose which chore you do first when both are equally unpleasant.
