Find the expected value of the optimal strategy.A college is holding a rock and roll concert to be held in the stadium and has sold out all tickets. If it rains, the show will have to be moved to the gym which has a smaller seating capacity. The college must decide in advance whether to set up seats and the stage in the gym, or in the stadium, or both, just in case.
