You have been asked to determine the probability that the contribution margin (revenue – variable cost) of a particular predict exceeds the fixed cost of $2000. The total number of units sold is normally distributed with a mean of 400 and a variance of 900. The selling price per unit is $10. The total number of units produced is normally distributed with a mean of 400 and a variance of 1600. The variable production cost per unit is $4. Production and sales have a correlation of .5 What is the probability that the contribution margin exceeds the fixed cost of $2000?
