Roommate B would like to use the hand signal with the highest probability of winning the game. What would you advise roommate B to use? You can simulate a play of the game by basing the game's result on roommate B's probability assignments. That is, the chance that roommate A chooses rock is P(RA), the chance that he chooses paper is P(PA), and the chance that he chooses scissors is P(SA), where P[RA), P(PA), and P(SA) have been previously determined. Okay, play it now! (Click the red PLAY! icon to reveal roommate A's choice.) PLAYI If roommate B took the advice to choose the highest probability of winning, then roommate B 9 20 F3 E # % A &4 assigning probability to events - Rock-paper scissors A common way for two people to settle a frivolous dispute is to play a game of rock-paper-scissors. In this game, each person Scissors simultaneously displays a hand signal to Indicate a rock, a piece bamis pope of paper, or a pair of scissors. Rock beats scissors, scissors beats paper, and paper beats rock. If both players select the same hand signal, the game results In a tie. Paper beats mori Two roommates, roommate A and roommate B, are about to go cruising with a mutual friend and are arguing over who gets to sit in the front seat. Roommate A suggests a game of rock-paper-scissors to settle the dispute. Rock beats scissors Consider the game of rock-paper-scissors to be a random experiment. How many outcomes are in the sample space of this random experiment? 0 9 0 12 0 2 0 5 Assume that both roommates' choices of rock, paper, or scissors are random, independent, and equally likely. Let RA, Ra, Pa. Pp. SA, and So 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 simple event consisting of roommates A and B both selecting rock be denoted parenthetically as (RA Ra), and so on for the other possibilities. Define event B as the event that roommate B wins the game and gets to sit in the front seat. Event B is composed of the following simple events: O B - ((Ra, Ral. (RA Po), (PA. 58). (54, Ral) O B - {(BA Sak, (PA. Re), (54, Pal) O B = (RA Pal, (PA.
