WitrynaThe mean of a discrete random variable is the weighted mean of the values. The formula is: μ x = x 1 *p 1 + x 2 *p 2 + hellip; + x 2 *p 2 = Σ x p. In other words, multiply each given value by the probability of getting that value, then add everything up. For continuous random variables, there isn’t a simple formula to find the mean. WitrynaWe see that with a high probability of approximately 0.95, the smallest number is 1, 2, or 3; the expectation is 1.75. The middle number can be 2, 3, 4, or 5; the expectation is …
