Webb3 sep. 2024 · To find the variance of this probability distribution, we need to first calculate the mean number of expected sales: μ = 10*.24 + 20*.31 + 30*0.39 + 40*0.06 = 22.7 sales. We could then calculate the variance as: The variance is the sum of the values in the third column. Thus, we would calculate it as: WebbIn probability, a random variable is a real valued function whose domain is the sample space of the random experiment.
