To construct sample spaces for experiments in which we deal with non-numerical data, we often code the various alternatives by assigning them numbers. For instance, if an engineer is asked to rate the performance of a new machine with respect to its replacement as poor, not satisfactory, no change, satisfactory, or excellent, we might assign these alternatives the codes, 1,2,3,4, and 5 . If P={1,2}, Q={4,5}, R={2,3}, and S={3,4,5}, express each of the following symbolically by listing its elemen
