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.

Problem 6 Five applicants for a job are ranked according to ability, with being the best. These rankings are unknown to an employer, who simply hires two applicants at random. What is the probability that this employer hires exactly one of the two best applicants? Problem 7 Five motors ( through 5) are available for use, and motor 2 is defective. Motors 1 and 2 come from supplier I, and motors 3, 4, and 5 come from supplierIL. Suppose two...

Four universities-1, 2, 3, and 4-are participating in a holiday basketball tournament. In the first round, 1 will play 2 and 3 will play 4. Then the two winners will play for the championship, and the two losers will also play. One possible outcome can be denoted by 1324 (1 beats 2 and 3 beats 4 in first-round games, and then 1 beats 3 and 2 beats 4). (Enter your answers in set notation. Enter EMPTY or for the empty...

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...

Michael has a box of colored balls. It contains two red balls, two green balls, two yellow balls, and five blue balls. Michael draws a ball at random from the box Let R denote the event that the ball he draws is red, and let B denote the event that the ball he draws is blue. What is Pr(R|B)? What is Pr(R|B′)? Enter your answers as whole numbers or fractions in lowest terms. A bag contains four 1-dollar bills, three...

There are two traffic lights on the route used by a certain individual to go from home to work. Let E denote the event that the individual must stop at the first light, and define the event F in a similar manner for the second light. Suppose that P(E) = 0.5, P(F) 0.2, and P(E n F) 0.12. (a) What is the probability that the individual must stop at at least one light; that is, what is the probability of...

There are two traffic lights on the route used by a certain individual to go from home to work. Let E denote the event that the individual must stop at the first light, and define the event F in a similar manner for the second light. Suppose that P(E) = 0.3, P(F) = 0.4, and P(E ∩ F) = 0.13. (a) What is the probability that the individual must stop at at least one light; that is, what is the...

1. A college has been given a sizable grant: enough to build either a new library or gymnasium. But, as there is only money enough to build one facility, the presiden wants to ask students which one they feel is in greater need of renovation. Suppose there are 500 male students and 400 female students in the school. a) What is the population under study? (2 points) b) The president wants to randomly ask 50% of the students. How many...
