Techware Incorporated is considering the introduction of two new software products to the market. The company has four options regarding these products: introduce neither product, introduce product 1 only, introduce product 2 only, or introduce both products. Research and development costs for products 1 and 2 are $180,000 and $150,000, respectively. Note that the first option entails no costs because research and development efforts have not yet begun. The success of these software products depends on the national economy in the coming year. The companys revenues, depending on its decision and the state of the economy, are given in the attached file. The probabilities of a strong, fair, or weak economy in the coming year are assessed to be 0.10, 0.60, and 0.30, respectively.
