# Expected value of expected value

Chapter 6. Expected Value and Variance. Expected Value of Discrete Random Variables. When a large collection of numbers is assembled, as in a census. Expected value. The concept of expected value of a random variable is one of the most important concepts in probability theory. It was first devised in the 17th. The mean or expected value of X is defined by E(X) = sum xk p(xk). Interpretations: (i) The expected value measures the center of the probability distribution.
You may need to use a sample space. I also like that it shows the possibility of winning multiple prizes. Then the expected value of this random variable is the infinite sum. Suppose random variable X can take value x 1 with probability p 1 , value x 2 with probability p 2 , and so on, up to value x k with probability p k. How to construct a probability distribution. The principle is that the value of a future gain should be directly proportional to the chance of getting it. They solved the problem in casino slots for free download computational ways but their results were identical because their dkfz casino were based on the same fundamental principle. This idea is much more powerful than might first appear.
