- 2) scrooge.py Scrooge McDuck is letting you into his vault full of pennies, nickels, dimes and quarters. He will let you play the following game: you can pick 8 coins at random, and if they sum to at least a dollar, you win, and can keep your money! But if you lose, you don't get to keep the money, AND have to pay Scrooge a dollar. (Each coin you pick is equally likely to be a penny, nickel, dime, or quarter.) Your job: using a simulation, estimate 1. the probability that you win (meaning your coins sum to more than a dollar), and 2. if you play this game over and over, the average amount you will win (where the amount you win in a game could be negative). Here is a bit more direction: you should simulate 100,000 plays of this game. Each simulated play should involve picking 8 different random numbers - each one should be .01, .05, .10, or .25, with each value equally likely - which represent the 8 coins being chosen; these should be summed each time. As you proceed through these…arrow_forwardDescription:Create a text based game like some of the following options. Game must have a 2 player, and play againstcomputerideas:Some kind of fill in game similar to a tic tac toe, but not tic tac toeHangman type game but not hangman exactlyA card game (like 31 or high card wins, etc)A question based game similar to Who wants to be amillionaireYour own game you inventedGame must:Keep score while the player continues to play. Start score over when a new game startsShow final score to player and allow player to enter a name if they earn the high score. Name and score mustbe written out to a highscore text file. If the player chooses to see high score the program must read it infrom that file and show the name and score.Offer a main menu showing:1. Rules2. Play Against Computer3. Play 2 Player Game4. See High Score5. QuitThe user must be able to keep playing until they decide to quit. Another menu of options should appear insidethe 1 and 2 player games.The high score must be written out…arrow_forwardYou have a pack of 5 randomly numbered cards, which can range from 0-9. You can win if you can produce a higher two-digit number from your cards than your opponent. Return true if your cards win that round. Examples winRound ([2, 5, 2, 6, 9], [3, 7, 3, 1, 2]) → true // Your cards can make the number 96 // Your opponent can make the number 73 // You win the round since 96 > 73 winRound ([2, 5, 2, 6, 9], [3, 7, 3, 1, 2]) → true winRound ([1, 2, 3, 4, 5], [9, 8, 7, 6, 5]) → false winRound ([4, 3, 4, 4, 5], [3, 2, 5, 4, 1]) → falsearrow_forward
- An argument is expressed in English below. Rhys will go to the beach. If Rhys is excited; then Rhys will go to the beach. Rhys is excited. Variable names are assigned to each English phrase as follows: p: Rhys is excited •q: Rhys will go to the beach Is the argument valid? If valid, then indicate which rule is used for the argument. If invalid, then give truth assignments to the variables that prove the argument is invalid. Pick 4. Check Nextarrow_forwardYou will build a simplified, one-player version of the classic board game Battleship! In this version of the game, there will be a single ship hidden in a random location on a 5 × 5 grid. The player will have 4 guesses at most to try to sink the ship. At each guess, the player names an attacking coordinate, that is (“guess row”, “guess col”). The game ends in two conditions: (1) the player is out of guesses; (2) the player hits the ship. Examples are given in Figure 1. The 5 × 5 board is shown every time the player inputs a guess entry. The ship takes only one entry of the board and it is randomly given before the player’s guesses. The player inputs guessing entries in the Python console. Entries missed the ship are replaced by “X” in the board. You must use loop in your code. Please submit your code and console screenshots to bartleby. Code contain- ing syntax error will be graded zero. Hints: 1 Create a variable board and set it equal to an empty list…arrow_forwardwhen coding a chess game, implement the following method: isInCheck(Side s): Returns true if the king of side s is attacked by any of the opponent’s pieces, i.e., if in the current board state, any of the opponents pieces can move to where the king is. Otherwise, it returns false. Note that this method is only used to warn the player when they are in check. You can use the GUI to test if this is working. public boolean isInCheck(Side side) { // TODO write this method return false; } public enum Side { BLACK, WHITE; public static Side negate(Side s) { return s == Side.BLACK ? Side.WHITE : Side.BLACK; } }arrow_forward
