Coin flips and events. 1)A coin is flipped four times. For each of the events described below, express the event as a set in roster notation. Each outcome is written as a string of length 4 from {H, T}, such as HHTH. Assuming the coin is a fair coin, give the probability of each event. (b) There are at least two consecutive flips that come up heads. (c) The first flip comes up tails and there are at least two consecutive flips that come up heads.
MONTY HALL LAB write this code in python and use # to answers questions - You are only allowed to use the following functions/methods: print(), range(), len(), sum(), max(), min(), and .append(). It is not mandatory to useall of these functions/methods. In this lab, you will write a code that simulates the Monty Hall Game Show. Thegame host gives the participant the choice of selecting one of three doors. Twodoors has a goat behind them and one door has a prize. The set of choices arerandomized each round. The participant needs to select the door with the prizebehind it. When the participant selects a door, the game host reveals a door with agoat behind it. The game host opens a door (different from the one selected by theparticipant) that has a goat behind it. The participant is then given the option tochange their choice. When you run your code, the code would display a message prompting the user toinput their door choice, labelled as 1, 2, and 3. Then the code will display a…

Specification: Read sentences from the user until * is entered. Show the number of words in each sentence that contain a stretch of non-z characters with exactly 2 vowels. A stretch starts from the start of the word or after a 'z'. A stretch terminates just before another 'z' or at the end of the word. Examples: 1. Matching words: zoo, azozooza, GONZALEZ 2. Non-matching words: ozo, azoooza The sentences contain no punctuation, the words are separated by one or more spaces, and the characters may be upper or lower case. Keep reading sentences until the user enters "*". Sample I/O: Sentence: azoooza azooza zoo azoo Matching words = 3 Sentence: GONZALEZ passes the ball to VAZQUEZ Matching words = 3 Sentence: azozototzeti Matching words = 1 Sentence: * Done

Assignment 1/ Reset to Starter Code 2. Problem 2: Product ID Numbers Saved Problem Description In this second problem, you will build on and extend the program created while solving the first problem. You will be expected to isolate both the product id number and company number from the barcode number of the item to be purchased by the customer. Input You will receive (from the user) the following as input (in order): • The first and last name of the customer (e.g., Eric Poitras) • The item to be purchased, identified through a barcode number (e.g., 1909238092) • The cost of the item to be purchased by the customer (e.g., 8.50) • The cash amount given by the customer (e.g., 10.00) Processing 1. Extract the product id and company id numbers 2. Print the data stored in each variable in the corresponding format Output 1. Customer (Last, First): {LAST} {FIRST} 2. Item Number (Product, Company): {PRODUCT} {COMPANY} 3. Item Cost: (COST} 4. Cast Amount: {CASH} Examples Input Output Eric…
3. Let S(x) be the statement "x studied for the exam" and H(x, y) be the statement "x scored higher than y in the exam," where the domain of x and y consists of all students in this class. Which logical expression corresponds to the following statement? "Every student in this class who studied for the exam scored higher in the exam than every student who did not study for the exam." a. VxVy (H (x, y) → (S(x) ^ ¬S(y))) b. VxVy(S(x)^¬S(y) ^ H (x, y)) c. VxVy((S(x) ^ ¬S(y)) → H (x, y)) d. VxVy((S(x) → ¬S(y)) → H (x, y))
Description: In a hypothetical class, students take two midterms and an optional final. If a student takes the final and gets in it a better score than the lowest of the two midterm scores, then the lowest midterm score would be replaced by the comprehensive final score. The overall score will then be calculated by averaging the three test scores. If the student does not take the optional final, the overall score is calculated using only the two midterm scores. Students’ exam scores are included in the “Question1” tab in the attached worksheet. Empty data entries for the optional comprehensive final means that the student did not take the optional final. Tasks: Task 1: In Question1_Module, code a function that requires midterm1 score, midterm2 score, and comprehensive final as inputs and calculate the overall score per the description above. Task 2: In Question1_Module, code a Sub that uses the function coded in task 1 to fill column ‘I’ of the worksheet and link this…

In C programming language write Task 2: Hangman gameWrite a terminal based on the game of Hangman. In a hangman game, the player is given a wordthat they need to guess, with each letter of the word represented by an underscore/blank. Theplayer tries to guess a letter of the word by entering it into the terminal. If the letter is correct, theblank corresponding to that letter is filled in. If the letter is incorrect, a part of a stick figure isdrawn. The player has a limited number of incorrect guesses before the stick figure is fully drawnand the game is lost. The player wins the game if they guess all the letters of the word before thestick figure is fully drawn.The program should have an array of possible words to choose from. A different word should berandomly chosen from the array every time we run the program.Others: Do not use GOTO statements
