2. demand for a product manufactured by apex consolidated varies from month to month. based on 2 years of data, the following probability distribution shows the companys monthly demand.
demand probability
300 .20
400 .30
500 .35
600 .15
a. if apex places monthly orders equal to the expected value of the monthly demand ,what should apex's monthly order quantity be for this product?
b. assume that each unit demanded generates $70 of revenue and that each unit ordered costs $50.00 how much will the company gain or lose in a month if it places an order based on your answer to part (a) and the actual demand for the item is 300 units?
c. what are the variance and standard deviation for the number of units demanded?
