We have the idea comes from the basic secretary problem, where its purpose is to select the the person suitable for the secretary position. And by M.P.Quine, we learn the strategies s=1 and s=2, where the value of s is defined as the overall rank of the price selected. Finally, we want to determine a mixed strategy that makes better profit and increases the probability of earning money. The mixed strategy is stable from the use of s=2 and is profitable from the use of s=1 and its extension.
