Answer:
C. As the number of repetitions of a probability experiment increases, the proportion with which a certain outcome is observed gets closer to 1. This applies to casinos because they are able to make a profit in the long run because they have a small statistical advantage in each game.
Step-by-step explanation:
In casinos there may be eventual winnings from gamblers, but thanks to the Law of Large Numbers, the casino has guaranteed winnings.
Casino games are "unequal games": the outcomes of each game always give the casino a small advantage. That is, the expected value of each game represents a profit for the casino.
In this way, although there may be a winning streak for some gambler, in the long run the result is going to be, with a very high probability, the theoretical outcome or expected value (a profit for the casino). A game repeated many times, as it will happen for a operating casino, will end up giving the expected winnings for the casino with a very small variance.
