Jan 2, 2025 · Expected Value: If O represents an outcome of an experiment and n (O) represents the value of that outcome, then the expected value of the experiment is: ∑ n (O) P (O)

For a discrete random variable, the expected value can be calculated by multiplying each numerical outcome by the probability of that outcome, and then summing those products together. The …

To find the expected value, E (X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products.

To keep things simple, we provide an informal definition of expected value and we discuss its computation in this lecture, while we relegate a more rigorous definition to the (optional) lecture …
