You have been asked to determine the probability that the contribution margin for a particular product line exceeds the fixed cost of $2590. The total number of units sold is a normally distributed random variable with a mean of 500 and a variance of 1600 X - N(500,1600). The selling price per unit is $11. The total number of units produced is a normally distributed random variable with a mean of 500 and a variance of 2500 Y -N(500,2500). The variable production cost is $6 per unit. Production and sales have a positive correlation of 0.50. What is the probability that the contribution margin for the product line exceeds the fixed cost of $2590
