A library has five copies of a certain textbook on reserve of which two copies (1 and 2) are hardcover books and the other three (3, 4, and 5) are softcover books. A student examines these books in random order, stopping only when a softcover book has been selected.
Display the possible outcomes in a tree diagram.

6. A college library has five copies of a certain text on reserve. Two copies (1 and 2) are first printings, and the other three (3, 4, and 5) are second printings. A student examines these books in random order, stopping only when a second printing has been selected. One possible outcome is 5, and another is 213 a. List the outcomes in . b. Let A denote the event that exactly one book must be examined. What outcomes are...
Question 1. A vaccine has a 13% probability of failing to prevent a certain disease. The probability of getting the disease if a person is not vaccinated is 30%. In a certain geographic region, 25% of the people get vaccinated. (4-2 187-31 6ed) a. Draw a tree diagram that represents the experiment above and show the probability in each of the branches and the probability of the final outcomes. b. If a person is selected at random in this region,...
In this project, you will construct an Object-Oriented framework for a library system. The library must have books, and it must have patrons. The patrons can check books out and check them back in. Patrons can have at most 3 books checked out at any given time, and can only check out at most one copy of a given book. Books are due to be checked back in by the fourth day after checking them out. For every 5 days...
Can somebody help me with the Use Case Diagram . I am confused of what I am suppose to do. Here are the instructions : Your team should produce a Use Case Diagram and the associated Use Case Descriptions/Narratives for all the use cases in the diagram. The resulting document should havethe “professional look” and produced by a word processor, graphics/presentation/drawing software, and/or a CASE tool (e.g., Microsoft Word, Microsoft PowerPoint, ArgoUML, Dia, Visual Paradigm, Visio, etc.). All project documentation...
Problem #3: Let A and B be two events on the sample space S. Then show that a. P(B) P(AOB)+P(AnB) b. If Bc A, then show that P(A)2 P(B) Show that P(A| B)=1-P(A|B) C. P(A) d. If A and B are mutually exclusive events then show that P(A| AUB) = PA)+P(B) Problem 4: If A and B are independent events then show that A and B are independent. If A and B are independent then show that A and B...
Python Consider the GUI below (3 Labels and 3 Radiobuttons) which has been produced with a Python program using the Tkinter library. You are required to write a Python program to produce this interactive GUI. Your GUI must replicate the example above as closely as possible, including the same widgets displayed in the sample positions on the GUI, using the same colours, shapes and relative sizes. (Note that the GUI border in the sample output does not need to be...
Write a Java program that deals a five-card poker hand and then determines which of the following hands are contained in it: high card, pairs, two pair, three of a kind, flush. Test only for those hands. Use the numbers from 0 to 51 to represent the cards of the poker deck. 1. To deal the cards, your main method should call a secondary method that selects a random card. The secondary method should accept 5 integers that represent the...
requires python to answer (a) A school library has 3 study rooms available for students to book during its opening hours, on a first-come-first-serve basis. Assume there is no pre-booking, that is, the study rooms can be booked only on the day of usage itself. A library staff should be able to select to perform one of the following actions: Book a room o If there is no available room, the message: No study room available currently is displayed and...
TO SU Part 1: Probability were cay 1. A question on a multiple-choice test has 10 questions each with 4 possible answers (a,b,c,d). a. What is the probability that you guess all the answers to the 10 questions correctly (carn 100%)? 2. If you ask three strangers about their birthdays, what is the probability a. All were born on Wednesday? b. What is the probability that all three were born in the same month? c. All were born on different...
Consider a disease, which has three states: "0 (healthy)."1" (impaired), "Z (disease) In state "Z when certain treatments are adopted, the state can be restored to be healthy C'O).When a subject is either at state "O" or 1", she/he can decide whether some preventive actions should be taken so that she/he will be in a new state "3. The state transition probabilities are as follows (5) Assume that the disease process is a first-order time homogenous Markov chain and it...
