Use the profit model developed in Example 12.1 to implement a financial simulation model for a new product proposal and determine a distribution of profits using the discrete distributions below for the unit cost, demand, and fixed costs. Price is fixed at $1,000. Unit costs are unknown and follow the distribution

Unit Cost	Probability
$400	0.20
$600	0.40
$700	0.25
$800	0.15

Demand is also variable and follows the following distribution:

Demand	Probability
120	0.25
140	0.50
160	0.25

Fixed costs are estimated to follow the distribution

Fixed Costs	Probability
$45,000	0.20
$50,000	0.50
$55,000	0.30

Simulate this model for 50 trials and a production quantity of 140. What is the average profit?

I am in need of figuring how to do the 50 trials as well!
