f.
A laborant in a laboratory does a number of antigen tests in one day. Write a program that
simulates the number of antigen tests done in a day in a laboratory, displays the number of
positives and negatives, and calculates the % of positives in one day. Your program needs
to first generate a random number that will show the number of tests done in a day. One
laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one).
Then for each of the tests, your program needs to generate a random number to show
whether they are positive or negative. In order to write this program, you need to have the
following three functions used by the main function:
test result (void): This function generates a test result. It should randomly
return either one or zero. 1 means positive test result and 0 means negative test result.
float positive percentage (int,int) : This function takes the total number of
positives and the total number of tests and returns the % of positives.…
You have been asked to write a program to play rock-paper-scissors.
Your program will ask the user to input a number 0, 1, or 2 to denote rock, paper, and scissors respectively.
Your program will then randomly generate a number 0, 1, or 2 to denote the computer’s hand.
The rules for the game are:
•A scissor can cut paper.
•A rock can knock a scissor.
•A piece of paper can wrap a rock.
Let the game run continuously until either the user or the computer wins 3 times, displaying the outcome of each hand. At the end of the game, display a message indicating whether the user or the computer wins
Helpful Hint:
import random
player2= random.randint(0, 2)
Write a program that reads in three integers and then determines and prints the largest and the smallest integers in the group. Use only the programming techniques you have learned in this chapter.

If there are two coordinate points of the line are given, then it is very easy to compute the line equation. Also you can find the distance between two points. Problem: Write a program to compute lines equation for a set of lines. The number of lines is read from the user. Each line is computed by generating two points randomly using Point2D API. In addition, distance between two points is computed. The program should display a table which include all information about each line. See sample runs below. Take into consideration: 1. Number of generated lines should be greater than zero. 2. Two point objects are constructed only once. Then just update the location of two points for each line using Point2D API methods. 3. x and y values of each point are generated randomly to be less than 100 and greater than 0. 4.
