"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."

"It's usually best to go to a casino with cash only; no credit cards, debit cards, or checkbooks. You don't want to be tempted to play with more money than you can afford."

"Usually, a roulette table will have two different balls of slightly different sizes. Dealers can choose which to use based on which is more comfortable. The size of the ball does not affect the outcome."

"Although roulette has a relatively high house edge, you can play for longer because an average table only sees about thirty spins an hour, compared to sixty games an hour for blackjack."
