Alice and Bob are playing a game in which each of them has three strategies, A, B, or C.
If their choices do not match (e.g., if Alice picks B and Bob picks C), then no money is
exchanged; otherwise Alice pays Bob $6 (if they both choose A), or $3 (if they both choose
B), or $1 (if they both choose C). Is this a zero-sum game? Find a mixed-strategy Nash
equilibrium for it. Is this the only equilibrium of this game?

Expert Solution

This is a zero sum game.

In mixed strategy Nash equilibrium, both Alice and Bob play A with probability (1/9), B with probability (2/9) and C with probability (6/9).

This is the only Nsh equilibrium of the game.

Question 1 - Game Theory Alice and Bob are playing a game of simultaneous moves where they are deciding which concert they will attend on Saturday night. Two musicians are performing that night locally, Artist 1 and Artist 2. Alice prefers to go to Artist 1 with Bob rather than Artist 2 with Bob, and she prefers going to Artist 2 with Bob rather than going to Artist 2 alone.

Alice and Bob bet 50 dollars with each other in a game in which their friend Charlie tosses a two-sided coin 3 times in a remote location. If Alice correctly predicts the majority face (i.e. the face which occurred the most often in the three tosses), she gets to keep Bob's money as well. Charlie calls them and lets them know that at least 1 heads has occurred.a) Assuming that the coin was fair, what is the probability that the...

:) Alice and Bob play the following game: in each round, Alice first rolls a single standard fair die. Bob then rolls a single standard fair die. If the difference between Bob’s roll and Alice's roll is at most one, Bob wins the round. Otherwise, Alice wins the round. (a) (5 points) What is the probability that Bob wins a single round? (b) (7 points) Alice and Bob play until one of them wins three rounds. The first player to...

Both Alice and Bob toss a fair coin three times. The probability that Alice records a different numbers of heads than Bob is given by A/B, where A and B are relatively prime integers (greatest common divisor is 1). Find A + B.

Alice and Bob play the following game. They toss 5 fair coins. If all tosses are Heads, Bob wins. If the number of Heads tosses is zero or one, Alice wins. Otherwise, they repeat, tossing five coins on each round, until the game is decided. (a) Compute the expected number of coin tosses needed to decide the game. (b) Compute the probability that Alice wins

Alice and Bob are have several piles of chips. On each turn they can either remove 1 or 2 chips from one pile, or split a pile into two nonempty piles. Players take turns and a player that cannot make a move loses. Find the value of the Sprague–Grundy function for positions with one pile made of n chips. (Please do not forget to prove correctness of your asnwer.)
