It has many applications, from insurance policies to making financial decisions, and it's one thing that the casinos and government agencies that run gambling operations and lotteries hope most people never learn about.

Tiene muchas aplicaciones, desde pólizas de seguros hasta la toma de decisiones financieras, y es una cosa que los casinos y agencias gubernamentales que ejecutan operaciones de juego y loterías esperan que la mayoría de la gente nunca aprenda.

This means that over the long term of doing an experiment over and over, you would expect this average. This “long-term average” is known as the mean or expected value of the experiment and is denoted by the Greek letter μμ . In other words, after conducting many trials of an experiment, you would expect this average value.

This is the measure one would see if the experiment was repeated a large number of times, namely E(X)=np, where n is the number of times the experiment occurred and p is the probability for the event to occur. If we tossed a coin 1500 times, and the random variable X, represents the number of heads observed, we would expect 750 heads, that is E(X)=750.
