A software company recently designed and developed a new service for its customers.  However, it needs to decide whether to launch the service next month or wait for six months. The company performs research and discovers the probability of success for both options, along with their potential revenue. It also learns the probability of failure and corresponding losses for each. *Option A: Launching the service next month has a 55% probability of success with potential revenue of $250,000. It has a 45% probability of failure with a potential loss of $125,000.* *Option B: Launching the service in six months has a 65% probability of success with potential revenue of $400,000. It has a 35% probability of failure with a potential loss of $200,000.* Which option should the company pursue?
In designing a new space vehicle, NASA needs to decide whether to provide 0, 1 or 2 backup systems for a critical component of the vehicle. The first backup system, if included, comes into use only if the original system fails.  The second backup system, if included, comes into use only if the original system and the first backup system both fail.  NASA engineers claim that each system, independent of the others, has a 1.5% chance of failing if called into use.  Each backup system costs $70,000 to produce and install within the vehicle.  Once the vehicle is in flight, the mission will be scrubbed (ended early) only if the original system and all backups fail.  The cost of a scrubbed mission, in addition to production costs, is assessed to be $5,000,000.  How many backup systems are needed to minimize NASA’s expected total cost?
A swim club is designing a new pool to replace its old pool. The new pool would need to last for 10 years since the club is planning on relocating after 10 years. A concrete shell would cost $85,000 and last for all 10 years. Another option is to install a vinyl liner that would cost only $70,000 to install. However, the vinyl is not guaranteed to last for all 10 years, and it has a 40% chance of breaking down. Repair of the vinyl would cost $40,000 and would extend the life of the vinyl liner to the 10-year mark. If both options are acceptable to the swim club, which one minimizes cost? Support your answer with drawing a decision tree and provide your calculation.
