Prove that the first player has a winning strategy for the game of Chomp, introduced in Example 12 in Section 1.8, if the initial board is two squares wide, that is, a 2 × n board. [Hint: Use strong induction. The first move of the first player should be to chomp the cookie in the bottom row at the far right.]
This is a combinatorics math counting problem:
Suppose you are playing a game of Yahtzee. You know that you play with 5 dice, each with 6 sides. Since the dice are all rolled at the same time, let the roll (5, 4, 3, 2, 1) to be equal to (2, 4, 5, 1, 3). Assume for this question that we will only be rolling the dice once.
(i) You are attempting to roll a full house (where 2 dice have the same number and 3 dice have the same different number; ex. (5, 5, 3, 3, 3)). How many ways can you roll a full house? (do not count any rolls where all 5 dice are the same number)
(ii) You are now attempting to roll 4 of a kind (4 dice have the same number and the 5th dice has a different number; ex. (1, 1, 1, 1, 6)). How many ways can you roll 4 of a kind? (do not count any rolls where all 5 dice are the same number)
(iii) Finally, you only have one section left, to roll 3 of a kind (3 dice have the same number and the last 2 dice have two different numbers; ex. (3, 3, 3, 5, 6)). How many ways can you…
“ You are dealt five cards from a standard deck of 52 cards. How many of these handshave at least one queenandat least one spade. ”He breaks this into two cases. In the first case, he looks at hands which contain the queen of spadesQ♠. There is 1 way of choosing the Queen of Spades, and51C4ways of choosing the other fourcards. In the second case, he will start by choosing a non-spade queen (3 ways) and a non-queenspade (12 ways). There are 50 cards remaining, so he also throws away the Queen of Spades sothat he doesn’t overlap case 1. This gives49C3ways of choosing the last three cards. He concludesthat the answer is51C4+ (3·12·49C3). His answer is incorrect. Explain why, and give the correctanswer.

This information is displayed in the 2-way contingency table below Suppose that you pick a student at random from the class, and you notice that the student you picked is someone you saw performing in the band last week. What is the probability that the student is also in the chorus?

The two players take turns removing coins from the pile, either 1, 2, or 3 coins at a time. The player removing the last coin loses. You will prove by strong induction that if each player plays the best strategy possible, the first player will win if n mod 4 € (0, 2, 3) and the second player will win if n mod 4 = 1. Formalization Before you do so, you will need to formalize the rules of the game and the conjecture you will be proving. The following notation is defined to support this process in Part 1 and your proof in Parts 2 and 3: • The two players are elements of the set A={0,1}. I.e. one of them is player 0 and the other is player 1. This notation is useful because if you call one player p, then the other is simply 1-p Three predicate functions are provided: turn, take, and wins: ● o For any player p in A and any n in N, turn(p,n) means that…arrow_forward2) In a TV show, there are three boxes. Red, Green, and Yellow. One of the boxes has a frog in it and the other 2 is empty. You are trying to avoid to open the box with the frog. Assume that you randomly selected a box, letť's say Green. The game host opens one of the unselected box, say Red, and showed there was no frog in it. The host knows which one includes the frog. Now the host proposes you the option of either staying at the box that you have chosen or change it to the remaining box, (Yellow in this case). What is the probability of finding the frog if you change your selection and if you don't change? Compare the results and make the decision about switching your initial selection.arrow_forward

Consider the following two person parlor game, which starts with n counters on the table in front of the two players. Players 1 and 2 move sequentially, player 1 moving first. When it is his turn to move, a player must remove either 1 or 2 counters from the table. The game ends when all the counters are removed, and the player who moves last wins the game. a) Suppose that n = 15. Solve the game by backwards induction. (Hint: let k be the number of counters left on the table. Focus on the winning positions the value of k where a player wins and losing positions for a player. Start with small values of k, i..c 'k = 1 and k = 2.) b) How would you generalize your answer in (a), so that for any n, you can determine which player wins the game in the backwards induction solution?.arrow_forwardAfter a day of skiing a family of six washes all of their ski-wear including their gloves.
