The outcomes of all alternatives and events are indicated by a matrix called “pay-off matrix”. When m indicate alternatives and n indicate events, m x n size matrix is obtained. S1, S2, S3, ... , Sm denote the alternatives, and N1, N2, N3, ... , Nn denote the events in the pay-off matrix. Combinations of each strategy and event are indicated by Oij notation. The correct answer is C.
