In probability theory, the expected value (often noted as E(x)) refers to the expected average value of a random variable one would expect to find if one could repeat the random variable process a large number of time. In other words, the expected value is a weighted average of all possible values in the experiment.
The Pascal distribution, named after French mathematician Blaise Pascal, is a special case of negative binomial distribution. A Pascal experiment calculates the number of Bernoulli trials needed to get `r` amount of successes.
Variables:
Equation:
E(x) = r/p
