3. QUESTION #3: It is January 1 and Justin Case, chief counsel for Chemgoo, is faced with a difficult problem. It seems that the firm has two related lawsuits for patent infringement. For each suit, the firm has the option of going to trial or settling out of court. The trial date for one of the suits, which we will identify as Suit 1, is scheduled for July 15 and the second suit (Suit 2) is scheduled for January 8, next year. Preparation costs for either trial are estimated at $10,000. However, if the firm prepares for both trials, the preparation costs of the second trial will be only $6,000. These costs can be avoided by settling out of court. If the firm wins Suit 1, it pays no penalty. If it loses, it pays a $200,000 penalty. Lawyers for the firm assess the probability of winning Suit 1 as 0.5. The firm has the option to settle out of court for $100,000. Suit 2 can be settled out of court for a cost of $60,000. Otherwise, a trial will result in one of three possible outcomes: (1) the suit is declared invalid and the firm pays no penalty; (2) the suit is found valid but with no infringement, and the firm pays a penalty of $50,000; or (3) the suit is found with infringement, and the firm pays a penalty of $90,000. The likelihood of these outcomes depends in general on the result of Suit 1. The judge will certainly view Suit 1 as an important precedent. The firm lawyers' assessment of the probability of the three possible outcomes of Suit 2 under three sets of possible conditions (relating to Suit 1) are presented in the following table.

What is the expected savings from the decision analysis done in parts (a), (b) and (c) above and this scenario?
