Three cooks Mohsin, Khurram, and Shahid bake a special kind of cake. In the restaurant where they work, Mohsin, bakes 55 percent of these cakes, Khurram bakes 25 percent and Shahid bakes 20 percent and with respective probabilities of 0.03, 0.02 and 0.05 they fail to rise. A cake is selected and fails to rise what is probability that it was backed by cook Khurram.
