With reference to Exercise 9.12, what randomized strategy will minimize Ms. Cooper’s maximum expected cost? 

In exercise

Ms. Cooper is planning to attend a convention in Honolulu, and she must send in her room reservation immediately. The convention is so large that the activities are held partly in Hotel X and partly in Hotel Y, and Ms. Cooper does not know whether the particular session she wants to attend will be held at Hotel X or Hotel Y. She is planning to stay only one night, which would cost her $ 66.00 at Hotel X and $ 62.40 at Hotel Y, and it will cost her an extra $ 6.00 for cab fare if she stays at the wrong hotel.
