You consider yourself a bit of an expert at playing rock-paper-scissors and estimate that the probability that you win any given game is 0.45. In a tournament that consists of playing 60 games of rock-paper-scissors let X be the random variable that is the of number games won. Assume that the probability of winning a game is independent of the results of previous games. You should use the normal approximation to the binomial to calculate the following probabilities. Give your answers as decimals to 4 decimal places. a)Find the probability that you win at least 30 of the games. P(X ? 30) = b)Find the probability that you win less than 23 games. P(X < 23) = c)Find the probability that you win between 25 and 30 games. P(25 ? X ? 30) =

You are playing rock, paper, scissors (RPS) with a friend. Because you are good at predicting your friend’s strategy, there is a 60% chance each time that you play her, that you win. You play 7 games of rock, paper scissors with your friend and would like to know how many of them you win. Use this information to answer the following questions. 1. What is the random variable in this example? a. X = number of times your friend...

1. You are playing rock, paper, scissors with a friend. Each time you win, your friend gives you a dollar. Each time you lose, you pay your friend a dollar. Both of you play optimally with a mixed strategy of playing rock, paper, and scissors exactly one-third of the time each in a completely unpredictable way. Suddenly, a third person enters the room and offers to pay your friend (not you) 50 cents each time your friend throws a rock....

Kim and Kanye are playing a single game of Rock-Paper-Scissors. They have complete information. The winner must pay the loser $1,000. If they make the same choice they each get nothing. What is the Nash equilibrium for the game?

Many of you probably played the game “Rock, Paper, Scissors” as a child. Consider the following variation of that game. Instead of two players, suppose three players play this game, and let us call these players A, B, and C. Each player selects one of these three items—Rock, Paper, or Scissors—independent of each other. Player A will win the game if all three players select the same item, for example, rock. Player B will win the game if exactly two...

In the game Rock Paper Scissors, two players simultaneously choose one of three options: rock, paper, or scissors. If both players choose the same option, then the result is a tie. However, if they choose differently, the winner is determined as follows: • Rock beats scissors, because a rock can break a pair of scissors. • Scissors beats paper, because scissors can cut paper. • Paper beats rock, because a piece of paper can cover a rock. Create a game...

Code the game of Rock, Paper, Scissors between a human player and the computer. You can check out the game on Wikipedia if you are not familiar with it. Create a 4 option menu with the human player choices, plus the option of exiting the game. Randomly determine the computer’s choice (although a great deal of AI research has gone in to determining the best computer move). • Loop the game until the human player exits. • Count the number...

ROCK, PAPER, SCISSORS Using C++, you will implement a class called Tool. It should have an int field called strength and a char field called type. You may make them either private or protected. The Tool class should also contain the function void setStrength(int), which sets the strength for the Tool. Create 3 more classes called Rock, Paper, and Scissors, which inherit from Tool. Each of these classes will need a default constructor that sets the strength to 1 and...

Suppose you play rock paper scissors against a computer: *you gain $1 for each win *you lose $1 for each lost if it is a tie, nothing happens you choose rock 50% of the time and the others 25% of the time let x be a random variable that represents the amount of money you earn after one game. (a) find the probability distribution of X (b) what is your average payoff after 20 games? (c) what is the standard...

Consider now the following two-player simultaneous-move game, called the rock-paper-scissors-lizard game. R stands for rock, P for paper, S for scissors, and L for lizard. R beats S but loses against P and L; P beats R but loses against S and L; S beats P and L but loses against R; L beats R and P but loses against S. The payoffs for winning is 1 and that for losing is -1; when both players choose the same strategy...
