Consider the game of rock-paper-scissors to be an experiment. How many outcomes are in the sample space of this experiment? 9 12 2 8 Assume that both roommates’ choices of rock, paper, or scissors are random, independent, and equally likely. Let RARA , RBRB , PAPA , PBPB , SASA , and SBSB denote roommate A choosing rock, roommate B choosing rock, roommate A choosing paper, roommate B choosing paper, roommate A choosing scissors, and roommate B choosing scissors, respectively. Additionally, let the sample point consisting of roommates A and B both selecting rock be denoted parenthetically as ( RARA , RBRB ), and so on for the other possibilities.
