Due to launching of new car models, Western Car Deals has lowered the prices on cars of older models in order to clear the "leftover inventory". With reduced prices, a salesman estimates the following probability distribution of total number of cars that will be sold at various prices (X) over next week: 1 3 4 0.05 0.15 0.35 0.25 0.20 *** .. Given the probability distribution above, what is the expected variance of Variable X?
