The demand for a product varies from month to month. Based on data from past years, the following probability density function shows the probabilities of MNM company’s monthly demand. Probabilities of MNM company's monthly demand Unit Demand P(X=x) 1200 0.19 2100 0.30 3300 0.40 3800 0.11 c) Calculate the standard deviation. d) Each unit produced costs the company $8.00, and each unit is sold for $25.00. How much will the company gain or lose in a month if they stock the expected number of units demanded but sell 2100 units?
