4) Roll the dice 2
Make a program that tests the probability of a certain score when rolling x dice. The user should be
able to choose to roll eg 4 dice and test the probability of a selected score eg 11. The program should
then do a number of simulations and answer how big the probability is for the selected score with as
many dice selected. There must be error checks so that you cannot enter incorrect sums, for
example, it is not possible to get the sum 3 if you roll 4 dice.
TarningsKast2
How many dices do you want to throw?
11
Which number do you want the probability for?
The probability the get the number 11 with 4 dices is 7.19%

PLEASE CODE IN PYTHON
The Penny Pitch game is popular in amusement parks. Pennies are tossed onto a board that has certain areas marked with different prizes. For example:
The prizes available on this board are puzzle, game, ball, poster, and doll. At the end of the game, if all of the squares that say BALL are covered by a penny, the player gets the ball. This is also true for the other prizes. The board is made up of 25 squares (5 x 5). Each prize appears on three randomly chosen squares so that 15 squares contain prizes.In Python, create a PennyPitch application that displays a Penny Pitch board (use [ and ] to indicate squares) with prizes randomly placed and then simulates ten pennies being randomly pitched onto the board. After the pennies have been pitched, the application should display a message indicating which prizes have been won, if any.
Debugging:
There are errors in the following code snippet. Locate and fix all the errors with your own comments
to get full credit for the question. Assume the goal of the program is to perform a simulation to
estimate the probability of rolling three of a kind in a single roll of three six-sided dice.

- 4. Area of a Rectangle • Write a program that compares the area of two rectangles. You can do this several ways. one way is to add the length and width of each rectangle to get it's area and then compare the two areas together. • The program should ask for the length and width of two rectangles and then tell the user which rectangle has the greater area, or if the areas are the same. • The area of a rectangle is the rectangle's length times its width. Name the source code file yourName HW4.py. • Test and run the program.

Conditions for this method to return false are given in the code. public boolean canMove(int x, int y, int destX, int destY, Side s){ /* TODO write a method that checks if a piece at coordinates x,y can move to coordinates destX,destY Conditions for false: - Origin or destination coordinates are outside the board - Piece at origin is null - If source and destination coordinates are the same - Piece at origin is not of the same side as s - You can check this using piece.getSide() - Piece cannot move to the destination by piece movement rules - You should check this using Piece.canMove(destX,…arrow_forwardHow to attempt? Question : The Card Game One day, Fred and his N friends were playing a card game in which each player throws a card with a number written on it. The cards are such that a number X is written on front of the card, and the negative of that number is written on the back side of the card. This game has the following rules: - Each of the N players is asked to throw a card. After all the N cards are thrown, Fred has to flip one or more cards in consecutive order, only once. Your task is to help Fred flip the cards in such a way that the sum of the numbers, on front face of the cards, is the maximum.arrow_forwardSee the sample outputs for more clarification.

- Correct answer will be upvoted else downvoted. Computer science. After painting the white cells of the board, you want to place the maximum number of dominoes on it, according to the following rules: each domino covers two adjacent cells; each cell is covered by at most one domino; if a domino is placed horizontally (it covers two adjacent cells in one of the rows), it should cover only red cells; if a domino is placed vertically (it covers two adjacent cells in one of the columns), it should cover only blue cells. Let the value of the board be the maximum number of dominoes you can place. Calculate the sum of values of the board over all 2w possible ways to paint it. Since it can be huge, print it modulo 998244353. Input The first line contains two integers n and m (1≤n,m≤3⋅105; nm≤3⋅105) — the number of rows and columns, respectively. Then n lines follow, each line contains a string of m characters. The j-th character in the i-th string is * if the j-th cell in the i-th row…arrow_forwardProblem D: Different Dice Game Consider the following game for two players: The first player rolls a pair of dice of fair six-sided dice. If the two dice show different numbers, the player's score is the larger of the two numbers. Otherwise, the player's score is the sum of the two numbers. At this point, the player is asked if they want to remove their lower die and re-roll one die. If they say no, the player keeps her score and their turn is over. If they say yes, then they roll one more die and the number showing on this die replaces the lower of the original two rolls. Then these two dice rolls are scored accordingly. (For example, if the initial roll was a 2 and 5, if the player doesn't roll again, she gets 5 points. If she does roll again and obtains a 4, her score is still 5. If she rolled again and obtained a 6, her score would be a 6. If she rollwed again and obtained a 5, her score would be a 10.)

- Colour trio def colour_trio(colours): This problem was inspired by the fun little Mathologer video “Secret of Row 10” whose fractal animation once again remind us about how moving from two to three often opens the barn door for the chaos horse to emerge and wildly gallop away. To start, look at three values imaginatively named “red”, “yellow” and “blue”. These names serve as colourful (heh) mnemonics that could just as well have been “foo”, “bar” and “baz”, so no connection to actual physical colours is intended or implied. Next, de0ine a simple mixing rule between these colours with a rule that says that whenever any colour is mixed with itself, the result is that same colour, whereas mixing two different colours always gives the third. For example, mixing blue to blue gives that same blue, whereas mixing blue to yellow gives red. Given the 0irst row of colours as a string of lowercase letters to denote these colours, this function should construct the rows below the 0irst row one at…arrow_forwardBroken Cabins Problem Statement: There is an Office consisting of m cabins enumerated from 1 to m. Each cabin is 1 meter long. Sadly, some cabins are broken and need to be repaired. You have an infinitely long repair tape. You want to cut some pieces from the tape and use them to cover all of the broken cabins. To be precise, a piece of tape of integer length t placed at some positions will cover segments 5,5+1-sit-1. You are allowed to cover non-broken cabins, it is also possible that some pieces of tape will overlap. Time is money, so you want to cut at most k continuous pieces of tape to cover all the broken cabins. What is the minimum total length of these pieces? Input Format The first line contains three integers n,m and k(1sns10°, namsloº, Isksn) - the number of broken cabins, the length of the stick and the maximum number of pieces you can use The second line contains n integers bl,b2,bn (Isbism) - the positions of the broken cabins. These integers are given in increasing…arrow_forwardArranging Pebbles Write a program that can arrange a group of pebbles into its designated position. We have 4 types of pebbles: Red, white, blue, and green colored pebbles.
