A persоn whо is аlwаys willing tо pаy the expected value in a gamble is:

Cоnsider а firm thаt hаs $10 in inventоry.  They are cоnsidering two options with respect to the storage of this inventory.  Option A would have them store the entire inventory in one warehouse.  If it stores its inventory in a single warehouse, they are exposed to the risk of fire.   Assume that there is a 50% chance of a fire occurring, which would destroy their entire inventory.  Assume also that there is a 50% chance of having no fire. What is the expected loss for option A?  [exA] Derive the amount of risk (C.O.V) associated with option A. (Please round your answer to two decimal place) [COVA] Option B would have them split their entire inventory evenly across two warehouses; in other words, they would store $5 inventory in each warehouse.  Assume now that each warehouse individually faces the same probability distribution for severity [i.e., a 50% chance of losing the entire inventory and a 50% chance of losing nothing]. What is the expected loss for option B? [exB] Derive the amount of risk (C.O.V) associated with option B. (Please round your answer to two decimal place) [COVB]
