Constructing a probability distribution for random variable, Practice: Constructing probability distributions, Probability models example: frozen yogurt, Valid discrete probability distribution examples, Probability with discrete random variable example, Practice: Probability with discrete random variables, Mean (expected value) of a discrete random variable, Practice: Mean (expected value) of a discrete random variable, Variance and standard deviation of a discrete random variable, Practice: Standard deviation of a discrete random variable. However, if the process is repeated long enough, the average of the outcomes are most likely to approach a long-run average, expected value or mean value. The expected value or mean of a discrete distribution is the long-run average of occurrences. The random variable, X, is defined as the sum of the obtained scores. The expected values of perfect information solved examples are given below. Expected value Investment problem: • You have 100 dollars and can invest into a stock. MU is equal to the expected value of x is equal to the summation of k equals 1 to n, x k times f of x k. So mu here, we use for the expected value, not to be confused with MU that we previously used for the mean of a population. Find the expected value of winnings for each game. Determine the probability distribution, the expected value and variance. We must realize that any one trial using a discrete random variable yields only one outcome.
