"Casino results are expressed as probabilities, usually as a decimal amount between zero and one where zero is impossible and one always happens. For example, the chance of a flipped coin being tails is 0.5."

"In shoe-dealt blackjack, you must use your hands to tell the dealer what you want to do. While you can also say your intention out loud, the hand signals are required for the security cameras."

"Turing a card over 10 times will statistically result in 5 reds and 5 blacks. If you bet $1 each time with this house edge, you would win $4.50 but lose $5. In the long run, you expect to lose $0.50, or 5% of your money."

"If you turn over a playing card, the chance it will be red is 0.5, or 50%. If the casino was fair, it would pay you $1 for a $1 bet. But if a casino pays you $0.90 instead, it has a 5% edge."

"Casinos issue dollar slot tokens for the same reason, they don't seem like real money. But of course they are worth a dollar and you should always think about them like real dollars, not tokens."
