How do we read the odds of dice, cards, and coin flips?
Flip a coin. Roll a die. Draw a card. Each one feels like a tiny gamble with the universe — but the universe is actually keeping very honest books. "Odds" are just a way of counting. Once you learn to count the right things, every coin, cube, and card stops feeling like magic and starts feeling like math wearing a costume.
Start with the simplest gambler in the world: a coin. It has two sides, and nothing about it favors one over the other. So we count the possibilities — two — and notice that one of them is "heads." That's the whole trick. Probability is the number of outcomes you want, divided by the total number of equally likely outcomes. One out of two. A clean fifty-fifty.
