"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."

"The mathematical probability of something happening is its true odds. Casinos maintain their advantage by paying players less than the true odds of their wins."

"The only game where the probabilities change is in blackjack, where every card dealt alters the probability of which card will be next. EV in blackjack can alternate between positive and negative."

"Two different roulette wheels exist: European wheels which have 36 numbers plus a single zero and a house edge of 2.63% and American wheels which have a zero and double-zero and a 5.26% casino edge."

"Dealers are prohibited from making any direct transactions with players. You must place your money on the table where the dealer will convert it to chips and place the chips in front of you."
