AB has developed two new products, Product A and Product B, but has insufficient resources to launch both products. The success of the products will depend on the extent of competitor reaction. There is a 30 percent chance that competitors will take no action, a 60 percent chance that they will launch a similar product and a 10 percent chance that they will launch a better product.  The profit/loss that will be earned by each of the products depending on the extent of competitor reaction is as follows:  Competitor reaction  Product A  Product B  No action  £500,000  £600,000  Launch a similar product  £300,000  £400,000  Launch a better product  (£100,000)  (£200,000)    Another option for AB would be to launch neither product. If it chooses this course of action there is a 50 percent chance that competitors will take no action and there will be no effect on the company’s profit. There is a 50 percent chance that competitors will launch a new product and company profits will reduce by £150,000.  Required:  a) Demonstrate, using a decision tree and based on expected value, the best course of action for the company.
