Expected value
In probability theory and statistics, the "expected value" of a discrete random variable is the sum of each possible outcome in an experiment multiplied by the probability of its outcome. In other words, the expected value is like a randomized trial repeated many times at the same opportunity, and the average of all the possible states is basically the same number as the expected value.
Law of large numbers
In mathematics and statistics, the law of large numbers is a law that describes the results of an experiment repeated a considerable number of times. According to this law, the larger the number of samples, the closer the average will be to the expected value. For example, if we flip a coin up, it is originally accidental which side of the coin will be up after it falls, but when we flip the coin up enough times, reaching tens of thousands or even hundreds of thousands of times, we will find that each side of the coin will be up about half of The Times. The accidental contains the inevitable.
Knowing the concepts of expected value and the law of large numbers, let's look at how casinos make money.
