Computer Fundamentals and Programming 2 Write a program that determines a student’s grade. The program will accept 3 scores and computes the average score. Determine the grade based on the following rules: - If the average score is equal or greater than 90, the grade is A. - If the average score is greater than or equal to 70 and less than 90, the grade is B. - If the average score is greater than or equal to 50 and less than 70, the grade is C. - If the average score is less than 50, the grade is F.

Background: Game Rules The rules to the (dice) game of Pig:  You will need 2 dice.  To Play: a. The players each take turns rolling two die. b. A player scores the sum of the two dice thrown (unless the roll contains a 1): If a single number 1 is thrown on either die, the score for that whole turn is lost (referred to as “Pigged Out”). A 1 on both dice is scored as 25. c. During a single turn, a player may roll the dice as many times as they desire. The score for a single turn is the sum of the individual scores for each dice roll. d. The first player to reach the goal score wins unless a player scores higher subsequently in the same round. Therefore, everyone in the game must have the same number of turns. Execution and User Input This program is quite interactive with the user(s) and will take in the following information; please review the sample input / output sessions for details; we describe them again here emphasizing input.

In Python Text-based adventure game: Pretend you are creating a text-based adventure game. At different points in the game, you want the user to select to fight, run, or hide from certain enemies. The selection variable must be sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. Add an if statement in the choice() function to make the correct selection.
Q7-Write a program that simulates a simple calculator. It reads two integers and a character. If the character is a +, the sum is printed; if it is a -, the difference is printed; if it is a *, the product is printed; if it is a /, the quotient is printed; and if it is a %, the remainder is printed. (Use a switch statement.)

Exercise I- Medicine Write a program that asks the user to enter the name of the medicine (t for ThroX, f for FeliX), his mass. The user should enter as well if he has a prescription or not. The program will calculate the dosage using: age and his ThroX without prescription -The max dosage should be 0.75 mL -The dosage = mass / 150 -The number of pills per day to take is 1 ThroX with prescription -The dosage =mass * 3 / 150 -The number of pills per day to take is 5 FeliX with prescription -The dosage = 0.77 mL FeliX without prescription -The dosage should be between 0.3 and 0.7 -The dosage = mass * 0.009 -The number of pills per day to take is 2 -The number of pills per day to take is 6 The program should display the dosage and the number of pills to be taken per day if the requirements are full filled, otherwise it display "Please check your doctor for a prescription". In case the medicine does not exist in the database, the program display “Your medicine is not in our database!"…
