Question 3 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 No action Launch a similar product Launch a better product Product A 500,000 300,000 (100,000) Product B 600,000 400,000 (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.
