Sobre o Coin Flip
"Let's flip for it" is the oldest fair decision procedure there is — and this coin never lands on its edge or rolls under the fridge. Flip once for a quick heads/tails, or flip up to 100 coins at once for probability lessons and statistics demos; the tool reports the split, keeps a session tally of heads vs tails, and runs on the browser's secure random source so each flip is a genuine 50/50.
